Master of Public Administration
The Master of Public Administration is a professional graduate degree in public administration, similar to the Master of Business Administration but with an emphasis on the issues of governance. The MPA program is a professional degree and a graduate degree for the public sector and it prepares individuals to serve as managers and policy analysts in the executive arm of local, state/provincial, federal/national government, in non-governmental organization and nonprofit sectors. Instruction includes the roles and principles of public administration. Through its history, the MPA degree has become more interdisciplinary by drawing from fields such as economics, law, political science, regional planning in order to equip MPA graduates with skills and knowledge covering a broad range of topics and disciplines relevant to the public sector. A core curriculum of a typical MPA program includes courses on microeconomics, public finance, research methods, policy analysis, managerial accounting, public management, geographic information systems, program evaluation.
MPA students may focus their studies on public sector fields such as urban planning, emergency management, health care, economic development, community development, non-profit management, environmental policy, cultural policy, criminal justice. MPA graduates serve in some important positions within the public sector including Prime Minister of Singapore Lee Hsien Loong, former UN Secretary General Ban Ki-Moon, former CIA Director David Petraeus, former president of Liberia Ellen Johnson Sirleaf, former president of Mexico Felipe Calderón, Foreign Minister of Serbia Vuk Jeremić, Chairman of the World Toilet Organization Jack Sim, former New York City Police Commissioner Raymond Kelly, former Secretary of Health and Human Services Kathleen Sebelius, former Treasurer of Australia Wayne Swan. Other notable MPA graduates include pilot Chesley Sullenberger. A Master of Public Administration can be acquired at various institutions. See List of schools offering MPA degrees.

Vice President of the United States
The Vice President of the United States is the second-highest officer in the executive branch of the U. S. federal government, after the President of the United States, ranks first in the presidential line of succession. The Vice President is an officer in the legislative branch, as President of the Senate. In this capacity, the Vice President presides over Senate deliberations, but may not vote except to cast a tie-breaking vote; the Vice President presides over joint sessions of Congress. The Vice President is indirectly elected together with the President to a four-year term of office by the people of the United States through the Electoral College. Section 2 of the Twenty-fifth Amendment, ratified in 1967, created a mechanism for intra-term vice presidential succession, establishing that vice presidential vacancies will be filled by the president and confirmed by both houses of Congress. Whenever a vice president had succeeded to the presidency or had died or resigned from office, the vice presidency remained vacant until the next presidential and vice presidential terms began.
The Vice President is a statutory member of the National Security Council, the Board of Regents of the Smithsonian Institution. The Office of the Vice President organises the vice president's official functions; the role of the vice presidency has changed since the office was created during the 1787 constitutional Convention. Over the past 100 years, the vice presidency has evolved into a position of domestic and foreign policy political power, is now seen as an integral part of a president's administration; as the Vice President's role within the executive branch has expanded, his role within the legislative branch has contracted. The Constitution does not expressly assign the vice presidency to any one branch, causing a dispute among scholars about which branch of government the office belongs to: 1) the executive branch; the modern view of the vice president as an officer of the executive branch is due in large part to the assignment of executive authority to the vice president by either the president or Congress.
Mike Pence of Indiana is the current Vice President of the United States. He assumed office on January 20, 2017. No mention of an office of vice president was made at the 1787 Constitutional Convention until near the end, when an 11-member committee on "Leftover Business" proposed a method of electing the chief executive. Delegates had considered the selection of the Senate's presiding officer, deciding that, "The Senate shall choose its own President," and had agreed that this official would be designated the executive's immediate successor, they had considered the mode of election of the executive but had not reached consensus. This all changed on September 4, when the committee recommended that the nation's chief executive be elected by an Electoral College, with each state having a number of presidential electors equal to the sum of that state's allocation of representatives and senators; the proposed presidential election process called for each state to choose members of the electoral college, who would use their discretion to select the candidates they individually viewed as best qualified.
Recognizing that loyalty to one's individual state outweighed loyalty to the new federation, the Constitution's framers assumed that individual electors would be inclined to choose a candidate from their own state over one from another. So they created the office of vice president and required that electors vote for two candidates, requiring that at least one of their votes must be for a candidate from outside the elector's state, believing that this second vote could be cast for a candidate of national character. Additionally, to guard against the possibility that some electors might strategically throw away their second vote in order to bolster their favorite son's chance of winning, it was specified that the first runner-up presidential candidate would become vice president. Creating this new office imposed a political cost on strategically discarded electoral votes, incentivizing electors to make their choices for president without resort to electoral gamesmanship and to cast their second ballot accordingly.
The resultant method of electing the president and vice president, spelled out in Article II, Section 1, Clause 3, allocated to each state a number of electors equal to the combined total of its Senate and House of Representatives membership. Each elector was allowed to vote for two people for president, but could not differentiate between their first and second choice for the presidency; the person receiving the greatest number of votes would be president, while the individual who received the next largest number of votes became vice president. If there were a tie for first or for second place, or if no one won a majority of votes, the president and vice president would be selected by means of contingent elections protocols stated in the clause; the emergence of political parties and nationally coordinated election campaigns during the 1790s soon frustrated this original plan. In the election of 1796, Federalist John Adams won the presidency, but his bitter rival, Democratic-Republican Thomas Jefferson came second and became vice president.
Thus, the president and vice president were from opposing parties.
Egypt the Arab Republic of Egypt, is a country spanning the northeast corner of Africa and southwest corner of Asia by a land bridge formed by the Sinai Peninsula. Egypt is a Mediterranean country bordered by the Gaza Strip and Israel to the northeast, the Gulf of Aqaba and the Red Sea to the east, Sudan to the south, Libya to the west. Across the Gulf of Aqaba lies Jordan, across the Red Sea lies Saudi Arabia, across the Mediterranean lie Greece and Cyprus, although none share a land border with Egypt. Egypt has one of the longest histories of any country, tracing its heritage back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, urbanisation, organised religion and central government. Iconic monuments such as the Giza Necropolis and its Great Sphinx, as well the ruins of Memphis, Thebes and the Valley of the Kings, reflect this legacy and remain a significant focus of scientific and popular interest. Egypt's long and rich cultural heritage is an integral part of its national identity, which has endured, assimilated, various foreign influences, including Greek, Roman, Ottoman Turkish, Nubian.
Egypt was an early and important centre of Christianity, but was Islamised in the seventh century and remains a predominantly Muslim country, albeit with a significant Christian minority. From the 16th to the beginning of the 20th century, Egypt was ruled by foreign imperial powers: The Ottoman Empire and the British Empire. Modern Egypt dates back to 1922, when it gained nominal independence from the British Empire as a monarchy. However, British military occupation of Egypt continued, many Egyptians believed that the monarchy was an instrument of British colonialism. Following the 1952 revolution, Egypt expelled British soldiers and bureaucrats and ended British occupation, nationalized the British-held Suez Canal, exiled King Farouk and his family, declared itself a republic. In 1958 it merged with Syria to form the United Arab Republic, which dissolved in 1961. Throughout the second half of the 20th century, Egypt endured social and religious strife and political instability, fighting several armed conflicts with Israel in 1948, 1956, 1967 and 1973, occupying the Gaza Strip intermittently until 1967.
In 1978, Egypt signed the Camp David Accords withdrawing from the Gaza Strip and recognising Israel. The country continues to face challenges, from political unrest, including the recent 2011 revolution and its aftermath, to terrorism and economic underdevelopment. Egypt's current government is a presidential republic headed by President Abdel Fattah el-Sisi, described by a number of watchdogs as authoritarian. Islam is the official religion of Egypt and Arabic is its official language. With over 95 million inhabitants, Egypt is the most populous country in North Africa, the Middle East, the Arab world, the third-most populous in Africa, the fifteenth-most populous in the world; the great majority of its people live near the banks of the Nile River, an area of about 40,000 square kilometres, where the only arable land is found. The large regions of the Sahara desert, which constitute most of Egypt's territory, are sparsely inhabited. About half of Egypt's residents live in urban areas, with most spread across the densely populated centres of greater Cairo and other major cities in the Nile Delta.
The sovereign state of Egypt is a transcontinental country considered to be a regional power in North Africa, the Middle East and the Muslim world, a middle power worldwide. Egypt's economy is one of the largest and most diversified in the Middle East, is projected to become one of the largest in the world in the 21st century. In 2016, Egypt became Africa's second largest economy. Egypt is a founding member of the United Nations, Non-Aligned Movement, Arab League, African Union, Organisation of Islamic Cooperation. "Miṣr" is the Classical Quranic Arabic and modern official name of Egypt, while "Maṣr" is the local pronunciation in Egyptian Arabic. The name is of Semitic origin, directly cognate with other Semitic words for Egypt such as the Hebrew "מִצְרַיִם"; the oldest attestation of this name for Egypt is the Akkadian "mi-iṣ-ru" related to miṣru/miṣirru/miṣaru, meaning "border" or "frontier". There is evidence of rock carvings in desert oases. In the 10th millennium BCE, a culture of hunter-gatherers and fishers was replaced by a grain-grinding culture.
Climate changes or overgrazing around 8000 BCE began to desiccate the pastoral lands of Egypt, forming the Sahara. Early tribal peoples migrated to the Nile River where they developed a settled agricultural economy and more centralised society. By about 6000 BCE, a Neolithic culture rooted in the Nile Valley. During the Neolithic era, several predynastic cultures developed independently in Upper and Lower Egypt; the Badarian culture and the successor Naqada series are regarded as precursors to dynastic Egypt. The earliest known Lower Egyptian site, predates the Badarian by about seven hundred years. Contemporaneous Lower Egyptian communities coexisted with their southern counterparts for more than two thousand years, remaining culturally distinct, but maintaining frequent contact through trade; the earliest known evidence of Egyptian hieroglyphic inscriptions appeared during the predynastic period on Naqada III pottery vessels, dated to about 3200 BCE. A unified kingdom was founded c. 3150 BCE
Cable-Satellite Public Affairs Network is an American cable and satellite television network, created in 1979 by the cable television industry as a nonprofit public service. It televises many proceedings of the United States federal government, as well as other public affairs programming; the C-SPAN network includes the television channels C-SPAN, C-SPAN2, C-SPAN3, the radio station WCSP-FM, a group of websites which provide streaming media and archives of C-SPAN programs. C-SPAN's television channels are available to 100 million cable and satellite households within the United States, while WCSP-FM is broadcast on FM radio in Washington, D. C. and is available throughout the U. S. on SiriusXM via Internet streaming, globally through apps for iOS, BlackBerry, Android devices. The network televises U. S. political events live and "gavel-to-gavel" coverage of the U. S. Congress, as well as occasional proceedings of the Canadian and British Parliaments and other major events worldwide, its coverage of political and policy events is unmoderated, providing the audience with unfiltered information about politics and government.
Non-political coverage includes historical programming, programs dedicated to non-fiction books, interview programs with noteworthy individuals associated with public policy. C-SPAN is a private, non-profit organization funded by its cable and satellite affiliates, it does not have advertisements on any of its networks, radio stations, or websites, nor does it solicit donations or pledges; the network operates independently, neither the cable industry nor Congress has control of its programming content. Brian Lamb, C-SPAN's chairman and former chief executive officer, first conceived the concept of C-SPAN in 1975 while working as the Washington, D. C. bureau chief of the cable industry trade magazine Cablevision. It was a time of rapid growth in the number of cable television channels available in the United States, Lamb envisioned a cable-industry financed nonprofit network for televising sessions of the U. S. Congress and other public affairs event and policy discussions. Lamb shared his idea with several cable executives.
Among them were Bob Rosencrans, who provided $25,000 of initial funding in 1979, John D. Evans, who provided the wiring and access to the headend needed for the distribution of the C-SPAN signal. C-SPAN was launched on March 19, 1979, in time for the first televised session made available by the House of Representatives, beginning with a speech by then-Tennessee representative Al Gore. Upon its debut, only 3.5 million homes were wired for C-SPAN, the network had just three employees. The second C-SPAN channel, C-SPAN2, followed on June 2, 1986 when the U. S. Senate permitted itself to be televised. C-SPAN3, the most recent expansion channel, began full-time operations on January 22, 2001, shows other public policy and government-related live events on weekdays along with weekend historical programming. C-SPAN3 is the successor of a digital channel called C-SPAN Extra, launched in the Washington D. C. area in 1997, televised live and recorded political events from 9:00 a.m. to 6:00 p.m. Eastern Time Monday through Friday.
C-SPAN Radio began operations on October 9, 1997, covering similar events as the television networks and simulcasting their programming. The station broadcasts on WCSP in Washington, D. C. is available on XM Satellite Radio channel 120 and is streamed live at c-span.org. It was available on Sirius Satellite Radio from 2002 to 2006. Lamb semi-retired in March 2012, coinciding with the channel's 33rd anniversary, gave executive control of the network to his two lieutenants, Rob Kennedy and Susan Swain. On January 12, 2017, the online feed for C-SPAN1 was interrupted and replaced by a feed from the Russian television network RT America for 10 minutes. C-SPAN announced that they were troubleshooting the incident and were "operating under the assumption that it was an internal routing issue." C-SPAN celebrated its 10th anniversary in 1989 with a three-hour retrospective, featuring Lamb recalling the development of the network. The 15th anniversary was commemorated in an unconventional manner as the network facilitated a series of re-enactments of the seven historic Lincoln-Douglas debates of 1858, which were televised from August to October 1994, have been rebroadcast from time to time since.
Five years the series American presidents: Life Portraits, which won a Peabody Award, served as a year-long observation of C-SPAN's 20th anniversary. In 2004, C-SPAN celebrated its 25th anniversary, by which time the flagship network was viewed in 86 million homes, C-SPAN2 was in 70 million homes and C-SPAN3 was in eight million homes. On the anniversary date, C-SPAN repeated the first televised hour of floor debate in the House of Representatives from 1979 and, throughout the month, 25th anniversary features included "then and now" segments with journalists who had appeared on C-SPAN during its early years. Included in the 25th anniversary was an essay contest for viewers to write in about how C-SPAN has influenced their life regarding community service. For example, one essay contest winner wrote about how C-SPAN's non-fiction book programming serves as a resource in his charitable mission to record non-fiction audio books for people who are blind. To commemorate 25 years of taking viewer telephone calls, in 2005, C-SPAN had a 25-hour "call-in marathon", from 8:00 pm.
Eastern Time on Friday, October 7, concluding at 9:00 pm. Eastern Time on Saturday, October 8; the network had a viewer essay contest, the winner of, invited to co-host an hour of the broadcast from C-SPAN's Capitol
Slobodan Milošević was a Yugoslav politician and the President of Serbia from 1989 to 1997 and President of the Federal Republic of Yugoslavia from 1997 to 2000. He led the Socialist Party of Serbia from its foundation in 1990, he rose to power as Serbian President after he and his supporters claimed the need to reform the 1974 Constitution of Yugoslavia due to both the marginalization of Serbia and its political incapacity to deter Albanian separatist unrest in the Serbian province of Kosovo. Milošević's presidency of Serbia and the Federal Republic of Yugoslavia was marked by several major reforms to Serbia's constitution from the 1980s to the 1990s that reduced the powers of the autonomous provinces in Serbia. In 1990 Serbia transitioned from a Titoist, one-party system to a multi-party system and attempted reforms to the 1974 Constitution of Yugoslavia; the constituent republics of the country split apart amid the outbreak of wars, the Federal Republic of Yugoslavia was founded by the former SFRY republics of Serbia and Montenegro.
Milošević negotiated the Dayton Agreement on behalf of the Bosnian Serbs, which ended the Bosnian War in 1995. In the midst of the NATO bombing of Yugoslavia in 1999, Milošević was charged by the International Criminal Tribunal for the former Yugoslavia with war crimes in connection to the wars in Bosnia and Kosovo. Milošević resigned from the Yugoslav presidency amid demonstrations, following the disputed presidential election of 24 September 2000, he was arrested by Yugoslav federal authorities on 31 March 2001 on suspicion of corruption, abuse of power, embezzlement. The initial investigation into Milošević faltered for lack of evidence, prompting the Serbian Prime Minister Zoran Đinđić to extradite him to the International Criminal Tribunal for the former Yugoslavia to stand trial for charges of war crimes instead. At the outset of the trial, Milošević denounced the Tribunal as illegal because it had not been established with the consent of the United Nations General Assembly. Milošević conducted his own defence in the five-year-long trial, which ended without a verdict when he died in his prison cell in The Hague on 11 March 2006.
Milošević, who suffered from heart ailments and hypertension, died of a heart attack. The Tribunal denied any responsibility for Milošević's death and stated that he had refused to take prescribed medicines and medicated himself instead. After Milošević's death, the International Court of Justice concluded separately in the Bosnian Genocide Case that there was no evidence linking him to genocide committed by Bosnian Serb forces during the Bosnian War. However, the Court did find that Milošević and others in Serbia had committed a breach of the Genocide Convention by failing to prevent the genocide from occurring and for not cooperating with the ICTY in punishing the perpetrators of the genocide, in particular General Ratko Mladić, for violating its obligation to comply with the provisional measures ordered by the Court. Milošević's rule has been described by observers as autocratic. Milošević had ancestral roots from the Lijeva Rijeka village in Podgorica and was of the Vasojevići clan from Montenegro.
He was born in Požarevac, four months after the Axis invasion of the Kingdom of Yugoslavia, raised during the Axis occupation of World War II. He had an older brother Borislav who would become a diplomat, his parents separated in the aftermath of the war. His father, the Serbian Orthodox theologian Svetozar Milošević, committed suicide in 1962. Svetozar's father Simeun was an officer in the Montenegrin Army. Milošević's mother Stanislava, a school teacher and an active member of the Communist Party, committed suicide in 1972, her brother Milisav Koljenšić was a major-general in the Yugoslav People's Army who committed suicide in 1963. Milošević went on to study law at the University of Belgrade's Law School, where he became the head of the ideology committee of the Yugoslav Communist League's student branch. While at the university, he befriended Ivan Stambolić, whose uncle Petar Stambolić had been a president of Serbian Executive Council; this was to prove a crucial connection for Milošević's career prospects, as Stambolić sponsored his rise through the SKJ hierarchy.
After his graduation in 1966, Milošević became an economic advisor to Mayor of Belgrade Branko Pešić. Five years he married his childhood friend, Mirjana Marković, with whom he had two children: Marko and Marija. Marković would have some influence on Milošević's political career both before and after his rise to power. In 1968, Milošević got a job at the Tehnogas company, where Stambolić was working, became its chairman in 1973. By 1978, Stambolić's sponsorship had enabled Milošević to become the head of Beobanka, one of Yugoslavia's largest banks, he was 6 feet 1¼ inches tall. On 16 April 1984, Milošević was elected president of the Belgrade League of Communists City Committee. On 21 February 1986 the Socialist Alliance of Working People unanimously supported him as presidential candidate for the SKJ's Serbian branch Central Committee. Milošević was elected by a majority vote at the 10th Congress of the Serbian League of Communists on 28 May 1986. Milošević emerged in 1987 as a force in Se
Harvard University is a private Ivy League research university in Cambridge, with about 6,700 undergraduate students and about 15,250 postgraduate students. Established in 1636 and named for its first benefactor, clergyman John Harvard, Harvard is the United States' oldest institution of higher learning, its history and wealth have made it one of the world's most prestigious universities; the Harvard Corporation is its first chartered corporation. Although never formally affiliated with any denomination, the early College trained Congregational and Unitarian clergy, its curriculum and student body were secularized during the 18th century, by the 19th century, Harvard had emerged as the central cultural establishment among Boston elites. Following the American Civil War, President Charles W. Eliot's long tenure transformed the college and affiliated professional schools into a modern research university. A. Lawrence Lowell, who followed Eliot, further reformed the undergraduate curriculum and undertook aggressive expansion of Harvard's land holdings and physical plant.
James Bryant Conant led the university through the Great Depression and World War II and began to reform the curriculum and liberalize admissions after the war. The undergraduate college became coeducational after its 1977 merger with Radcliffe College; the university is organized into eleven separate academic units—ten faculties and the Radcliffe Institute for Advanced Study—with campuses throughout the Boston metropolitan area: its 209-acre main campus is centered on Harvard Yard in Cambridge 3 miles northwest of Boston. Harvard's endowment is worth $39.2 billion, making it the largest of any academic institution. Harvard is a large residential research university; the nominal cost of attendance is high, but the university's large endowment allows it to offer generous financial aid packages. The Harvard Library is the world's largest academic and private library system, comprising 79 individual libraries holding over 18 million items; the University is cited as one of the world's top tertiary institutions by various organizations.
Harvard's alumni include eight U. S. presidents, more than thirty foreign heads of state, 62 living billionaires, 359 Rhodes Scholars, 242 Marshall Scholars. As of October 2018, 158 Nobel laureates, 18 Fields Medalists, 14 Turing Award winners have been affiliated as students, faculty, or researchers. In addition, Harvard students and alumni have won 10 Academy Awards, 48 Pulitzer Prizes and 108 Olympic medals, have founded a large number of companies worldwide. Harvard was established in 1636 by vote of the Great and General Court of the Massachusetts Bay Colony. In 1638, it acquired British North America's first known printing press. In 1639, it was named Harvard College after deceased clergyman John Harvard, an alumnus of the University of Cambridge, who had left the school £779 and his scholar's library of some 400 volumes; the charter creating the Harvard Corporation was granted in 1650. A 1643 publication gave the school's purpose as "to advance learning and perpetuate it to posterity, dreading to leave an illiterate ministry to the churches when our present ministers shall lie in the dust".
It offered a classic curriculum on the English university model—many leaders in the colony had attended the University of Cambridge—but conformed to the tenets of Puritanism. It was never affiliated with any particular denomination, but many of its earliest graduates went on to become clergymen in Congregational and Unitarian churches; the leading Boston divine Increase Mather served as president from 1685 to 1701. In 1708, John Leverett became the first president, not a clergyman, marking a turning of the college from Puritanism and toward intellectual independence. Throughout the 18th century, Enlightenment ideas of the power of reason and free will became widespread among Congregational ministers, putting those ministers and their congregations in tension with more traditionalist, Calvinist parties; when the Hollis Professor of Divinity David Tappan died in 1803 and the president of Harvard Joseph Willard died a year in 1804, a struggle broke out over their replacements. Henry Ware was elected to the chair in 1805, the liberal Samuel Webber was appointed to the presidency of Harvard two years which signaled the changing of the tide from the dominance of traditional ideas at Harvard to the dominance of liberal, Arminian ideas.
In 1846, the natural history lectures of Louis Agassiz were acclaimed both in New York and on the campus at Harvard College. Agassiz's approach was distinctly idealist and posited Americans' "participation in the Divine Nature" and the possibility of understanding "intellectual existences". Agassiz's perspective on science combined observation with intuition and the assumption that a person can grasp the "divine plan" in all phenomena; when it came to explaining life-forms, Agassiz resorted to matters of shape based on a presumed archetype for his evidence. This dual view of knowledge was in concert with the teachings of Common Sense Realism derived from Scottish philosophers Thomas Reid and Dugald Stewart, whose works were part of the Harvard curriculum at the time; the popularity of Agassiz's efforts to "soar with Plato" also derived from other writings to which Harvard students
United States Air Force
The United States Air Force is the aerial and space warfare service branch of the United States Armed Forces. It is one of the five branches of the United States Armed Forces, one of the seven American uniformed services. Formed as a part of the United States Army on 1 August 1907, the USAF was established as a separate branch of the U. S. Armed Forces on 18 September 1947 with the passing of the National Security Act of 1947, it is the youngest branch of the U. S. Armed Forces, the fourth in order of precedence; the USAF is the largest and most technologically advanced air force in the world. The Air Force articulates its core missions as air and space superiority, global integrated intelligence and reconnaissance, rapid global mobility, global strike, command and control; the U. S. Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense; the Air Force, through the Department of the Air Force, is headed by the civilian Secretary of the Air Force, who reports to the Secretary of Defense, is appointed by the President with Senate confirmation.
The highest-ranking military officer in the Air Force is the Chief of Staff of the Air Force, who exercises supervision over Air Force units and serves as one of the Joint Chiefs of Staff. Air Force components are assigned, as directed by the Secretary of Defense, to the combatant commands, neither the Secretary of the Air Force nor the Chief of Staff of the Air Force have operational command authority over them. Along with conducting independent air and space operations, the U. S. Air Force provides air support for land and naval forces and aids in the recovery of troops in the field; as of 2017, the service operates more than 5,369 military aircraft, 406 ICBMs and 170 military satellites. It has a $161 billion budget and is the second largest service branch, with 318,415 active duty airmen, 140,169 civilian personnel, 69,200 reserve airmen, 105,700 Air National Guard airmen. According to the National Security Act of 1947, which created the USAF: In general, the United States Air Force shall include aviation forces both combat and service not otherwise assigned.
It shall be organized and equipped for prompt and sustained offensive and defensive air operations. The Air Force shall be responsible for the preparation of the air forces necessary for the effective prosecution of war except as otherwise assigned and, in accordance with integrated joint mobilization plans, for the expansion of the peacetime components of the Air Force to meet the needs of war. §8062 of Title 10 US Code defines the purpose of the USAF as: to preserve the peace and security, provide for the defense, of the United States, the Territories and possessions, any areas occupied by the United States. The stated mission of the USAF today is to "fly and win...in air and cyberspace". "The United States Air Force will be a trusted and reliable joint partner with our sister services known for integrity in all of our activities, including supporting the joint mission first and foremost. We will provide compelling air and cyber capabilities for use by the combatant commanders. We will excel as stewards of all Air Force resources in service to the American people, while providing precise and reliable Global Vigilance and Power for the nation".
The five core missions of the Air Force have not changed since the Air Force became independent in 1947, but they have evolved, are now articulated as air and space superiority, global integrated intelligence and reconnaissance, rapid global mobility, global strike, command and control. The purpose of all of these core missions is to provide, what the Air Force states as, global vigilance, global reach, global power. Air superiority is "that degree of dominance in the air battle of one force over another which permits the conduct of operations by the former and its related land, sea and special operations forces at a given time and place without prohibitive interference by the opposing force". Offensive Counterair is defined as "offensive operations to destroy, disrupt, or neutralize enemy aircraft, launch platforms, their supporting structures and systems both before and after launch, but as close to their source as possible". OCA is the preferred method of countering air and missile threats since it attempts to defeat the enemy closer to its source and enjoys the initiative.
OCA comprises attack operations, sweep and suppression/destruction of enemy air defense. Defensive Counter air is defined as "all the defensive measures designed to detect, identify and destroy or negate enemy forces attempting to penetrate or attack through friendly airspace". A major goal of DCA operations, in concert with OCA operations, is to provide an area from which forces can operate, secure from air and missile threats; the DCA mission comprises both passive defense measures. Active defense is "the employment of limited offensive action and counterattacks to deny a contested area or position to the enemy", it includes both ballistic missile defense and air-breathing threat defense, encompasses point defense, area defense, high-value airborne asset defense. Passive defense is "measures taken to reduce the probability of and to minimize the effects of damage caused by hostile action without the intention of taking the initiative", it includes warning.
