A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or from a combination of fission and fusion reactions. Both bomb types release large quantities of energy from small amounts of matter; the first test of a fission bomb released an amount of energy equal to 20,000 tons of TNT. The first thermonuclear bomb test released energy equal to 10 million tons of TNT. A thermonuclear weapon weighing little more than 2,400 pounds can release energy equal to more than 1.2 million tons of TNT. A nuclear device no larger than traditional bombs can devastate an entire city by blast and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been used twice in war, both times by the United States against Japan near the end of World War II. On August 6, 1945, the U. S. Army Air Forces detonated a uranium gun-type fission bomb nicknamed "Little Boy" over the Japanese city of Hiroshima.
S. Army Air Forces detonated a plutonium implosion-type fission bomb nicknamed "Fat Man" over the Japanese city of Nagasaki; these bombings caused injuries that resulted in the deaths of 200,000 civilians and military personnel. The ethics of these bombings and their role in Japan's surrender are subjects of debate. Since the atomic bombings of Hiroshima and Nagasaki, nuclear weapons have been detonated over two thousand times for testing and demonstration. Only a few nations are suspected of seeking them; the only countries known to have detonated nuclear weapons—and acknowledge possessing them—are the United States, the Soviet Union, the United Kingdom, China, India and North Korea. Israel is believed to possess nuclear weapons, though, in a policy of deliberate ambiguity, it does not acknowledge having them. Germany, Turkey and the Netherlands are nuclear weapons sharing states. South Africa is the only country to have independently developed and renounced and dismantled its nuclear weapons.
The Treaty on the Non-Proliferation of Nuclear Weapons aims to reduce the spread of nuclear weapons, but its effectiveness has been questioned, political tensions remained high in the 1970s and 1980s. Modernisation of weapons continues to this day. There are two basic types of nuclear weapons: those that derive the majority of their energy from nuclear fission reactions alone, those that use fission reactions to begin nuclear fusion reactions that produce a large amount of the total energy output. All existing nuclear weapons derive some of their explosive energy from nuclear fission reactions. Weapons whose explosive output is from fission reactions are referred to as atomic bombs or atom bombs; this has long been noted as something of a misnomer, as their energy comes from the nucleus of the atom, just as it does with fusion weapons. In fission weapons, a mass of fissile material is forced into supercriticality—allowing an exponential growth of nuclear chain reactions—either by shooting one piece of sub-critical material into another or by compression of a sub-critical sphere or cylinder of fissile material using chemically-fueled explosive lenses.
The latter approach, the "implosion" method, is more sophisticated than the former. A major challenge in all nuclear weapon designs is to ensure that a significant fraction of the fuel is consumed before the weapon destroys itself; the amount of energy released by fission bombs can range from the equivalent of just under a ton to upwards of 500,000 tons of TNT. All fission reactions generate the remains of the split atomic nuclei. Many fission products are either radioactive or moderately radioactive, as such, they are a serious form of radioactive contamination. Fission products are the principal radioactive component of nuclear fallout. Another source of radioactivity is the burst of free neutrons produced by the weapon; when they collide with other nuclei in surrounding material, the neutrons transmute those nuclei into other isotopes, altering their stability and making them radioactive. The most used fissile materials for nuclear weapons applications have been uranium-235 and plutonium-239.
Less used has been uranium-233. Neptunium-237 and some isotopes of americium may be usable for nuclear explosives as well, but it is not clear that this has been implemented, their plausible use in nuclear weapons is a matter of dispute; the other basic type of nuclear weapon produces a large proportion of its energy in nuclear fusion reactions. Such fusion weapons are referred to as thermonuclear weapons or more colloquially as hydrogen bombs, as they rely on fusion reactions between isotopes of hydrogen. All such weapons derive a significant portion of their energy from fission reactions used to "trigger" fusion reactions, fusion reactions can themselves trigger additional fission reactions. Only six countries—United States, United Kingdom, China and India—have conducted thermonuclear weapon tests. North Korea claims to have tested a fusion weapon as of January 2016. Thermonuclear weapons a
United States Office of War Information
The United States Office of War Information was a United States government agency created during World War II. OWI operated from June 1942 until September 1945. Through radio broadcasts, posters, photographs and other forms of media, the OWI was the connection between the battlefront and civilian communities; the office established several overseas branches, which launched a large-scale information and propaganda campaign abroad. President Franklin D. Roosevelt promulgated the OWI on June 13, 1942 by Executive Order 9182; the Executive Order consolidated the functions of the Office of Facts and Figures, the Office of Government Reports, the Division of Information of the Office for Emergency Management. The Foreign Information Service, a division of the Office of the Coordinator of Information, became the core of the Overseas Branch of the OWI. At the onset of World War II, the American public was in the dark regarding wartime information. One American observer noted: “It all seemed to boil down to three bitter complaints…first, that there was too much information.
Further, the American public confessed a lack of understanding as to why the world was at war, held great resentment against other Allied Nations. President Roosevelt established the OWI to both meet the demands for news and less confusion, as well as resolve American apathy towards the war; the OWI's creation was not without controversy. The American public, the United States Congress in particular, were wary of propaganda for several reasons. First, the press feared a centralized agency as the sole distributor of wartime information. Second, Congress feared an American propaganda machine that could resemble Joseph Goebbels’ operation in Nazi Germany. Third, previous attempts at propaganda under the Committee on Public Information/Creel Committee during WWI were viewed as a failure, and fourth, America was experiencing endemic isolationism and was hesitant to become involved in a global propaganda campaign and subsequently a global war. But in the wake of the attack on Pearl Harbor, the need for coordinated and properly disseminated wartime information from the military/administration to the public outweighed the fears associated with American propaganda.
President Roosevelt entrusted the OWI to beloved journalist and CBS newsman Elmer Davis, with the mission to take “an active part in winning the war and in laying the foundations for a better postwar world”. President Roosevelt ordered Davis to “formulate and carry out, through the use of press, motion picture, other facilities, information programs designed to facilitate the development of an informed and intelligent understanding, at home and abroad, of the status and progress of the war effort and of the war policies and aims of the Government”; the OWI's operations were thus divided between the Overseas Branches. The OWI Domestic Radio Bureau produced series such as This is Our Enemy, which dealt with Germany and Italy; the radio producer Norman Corwin produced several series for OWI, including An American in England, An American in Russia, Passport for Adams, which starred Robert Young, Ray Collins, Paul Stewart and Harry Davenport. In 1942 OWI established the Voice of America, which remains in service as of 2018 as the official government broadcasting service of the United States.
The VOA borrowed transmitters from the commercial networks. The programs OWI produced included those provided by the Labor Short Wave Bureau, whose material came from the American Federation of Labor and the Congress of Industrial Organizations. In conjunction with the War Relocation Authority, the OWI produced a series of documentary films related to the internment of Japanese Americans. Japanese Relocation and several other films were designed to educate the general public on the internment, to counter the tide of anti-Japanese sentiment in the country, to encourage Japanese-American internees to resettle outside camp or to enter military service; the OWI worked with camp newspapers to disseminate information to internees. During 1942 and 1943 the OWI boasted two photographic units whose photographers documented the country's mobilization during the early years of the war, concentrating on such topics as aircraft factories and women in the workforce. In addition, the OWI produced a series of 267 newsreels in 16 mm film, The United Newsreel which were shown overseas and to US audiences.
These newsreels incorporated U. S. military footage. For examples see this Google list; the OWI Bureau of Motion Pictures worked with the Hollywood movie studios to produce films that advanced American war aims. According to Elmer Davis, "The easiest way to inject a propaganda idea into most people’s minds is to let it go through the medium of an entertainment picture when they do not realize that they are being propagandized." Successful films depicted the Allied armed forces as valiant "Freedom fighters", advocated for civilian participation, such as conserving fuel or donating food to troops. By July 1942 OWI administrators realized that the best way to reach American audiences was to present war films in conjunction with feature films. OWI's presence in Hollywood deepened throughout World War II, by 1943 every major Hollywood studio allowed the OWI to examine their film scripts. OWI evaluated; the Overseas Branch enjoyed less controversy than the Domestic Branch. Abroad, the
New Mexico is a state in the Southwestern region of the United States of America. It is one of the Mountain States and shares the Four Corners region with Utah and Arizona. With a population around two million, New Mexico is the 36th state by population. With a total area of 121,592 sq mi, it is the fifth-largest and sixth-least densely populated of the 50 states. Due to their geographic locations and eastern New Mexico exhibit a colder, alpine climate, while western and southern New Mexico exhibit a warmer, arid climate; the economy of New Mexico is dependent on oil drilling, mineral extraction, dryland farming, cattle ranching, lumber milling, retail trade. As of 2016–2017, its total gross domestic product was $95 billion with a GDP per capita of $45,465. New Mexico's status as a tax haven yields low to moderate personal income taxes on residents and military personnel, gives tax credits and exemptions to favorable industries; because of this, its film industry contributed $1.23 billion to its overall economy.
Due to its large area and economic climate, New Mexico has a large U. S. military presence marked notably with the White Sands Missile Range. Various U. S. national security agencies base their research and testing arms in New Mexico such as the Sandia and Los Alamos National Laboratories. During the 1940s, Project Y of the Manhattan Project developed and built the country's first atomic bomb and nuclear test, Trinity. Inhabited by Native Americans for many thousands of years before European exploration, it was colonized by the Spanish in 1598 as part of the Imperial Spanish viceroyalty of New Spain. In 1563, it was named Nuevo México after the Aztec Valley of Mexico by Spanish settlers, more than 250 years before the establishment and naming of the present-day country of Mexico. After Mexican independence in 1824, New Mexico became a Mexican territory with considerable autonomy; this autonomy was threatened, however, by the centralizing tendencies of the Mexican government from the 1830s onward, with rising tensions leading to the Revolt of 1837.
At the same time, the region became more economically dependent on the United States. At the conclusion of the Mexican–American War in 1848, the United States annexed New Mexico as the U. S. New Mexico Territory, it was admitted to the Union as the 47th state on January 6, 1912. Its history has given New Mexico the highest percentage of Hispanic and Latino Americans, the second-highest percentage of Native Americans as a population proportion. New Mexico is home to part of the Navajo Nation, 19 federally recognized Pueblo communities of Puebloan peoples, three different federally recognized Apache tribes. In prehistoric times, the area was home to Ancestral Puebloans and the modern extant Comanche and Utes inhabited the state; the largest Hispanic and Latino groups represented include the Hispanos of New Mexico and Mexican Americans. The flag of New Mexico features the state's Spanish origins with the same scarlet and gold coloration as Spain's Cross of Burgundy, along with the ancient sun symbol of the Zia, a Puebloan tribe.
These indigenous, Mexican and American frontier roots are reflected in the eponymous New Mexican cuisine and the New Mexico music genre. New Mexico received its name long before the present-day nation of Mexico won independence from Spain and adopted that name in 1821. Though the name “Mexico” itself derives from Nahuatl, in that language it referred to the heartland of the Empire of the Mexicas in the Valley of Mexico far from the area of New Mexico, Spanish explorers used the term “Mexico” to name the region of New Mexico in 1563. In 1581, the Chamuscado and Rodríguez Expedition named the region north of the Rio Grande "San Felipe del Nuevo México"; the Spaniards had hoped to find wealthy indigenous Mexica cultures there similar to those of the Aztec Empire of the Valley of Mexico. The indigenous cultures of New Mexico, proved to be unrelated to the Mexicas, they were not wealthy, but the name persisted. Before statehood, the name "New Mexico" was applied to various configurations of the U.
S. territory, to a Mexican state, to a province of New Spain, all in the same general area, but of varying extensions. With a total area of 121,699 square miles, the state is the fifth-largest state of the US, larger than British Isles. New Mexico's eastern border lies along 103°W longitude with the state of Oklahoma, 2.2 miles west of 103°W longitude with Texas. On the southern border, Texas makes up the eastern two-thirds, while the Mexican states of Chihuahua and Sonora make up the western third, with Chihuahua making up about 90% of that; the western border with Arizona runs along the 109° 03'W longitude. The southwestern corner of the state is known as the Bootheel; the 37°N parallel forms the northern boundary with Colorado. The states of New Mexico, Colorado and Utah come together at the Four Corners in New Mexico's northwestern corner. New Mexico has no natural water sources
The Potsdam Conference was held at Cecilienhof, the home of Crown Prince Wilhelm in Potsdam, occupied Germany, from 17 July to 2 August 1945. The participants were the Soviet Union, the United Kingdom, the United States, represented by Communist Party General Secretary Joseph Stalin, Prime Ministers Winston Churchill and Clement Attlee, President Harry S. Truman. Stalin and Truman gathered to decide how to administer Germany, which had agreed to unconditional surrender nine weeks earlier on 8 May; the goals of the conference included the establishment of postwar order, peace treaty issues, countering the effects of the war. A number of changes had taken place in the five months since the Yalta Conference which affected the relationships among the leaders; the Soviet Union was occupying Eastern Europe. Stalin had set up a puppet Communist government in Poland, he insisted that his control of Eastern Europe was a defensive measure against possible future attacks, claiming that it was a legitimate sphere of Soviet influence.
Second, Britain had a new Prime Minister. Conservative Party leader Winston Churchill had served as Prime Minister in a coalition government. A general election had been held in the UK on 5 July; the outcome became known during the conference when Labour leader Clement Attlee became the new Prime Minister. Third, President Roosevelt had died on 12 April 1945, Vice President Harry Truman assumed the presidency. During the war and in the name of Allied unity, Roosevelt had brushed off warnings of a potential domination by Stalin in part of Europe, he explained, "I just have a hunch that Stalin is not that kind of a man." "I think that if I give him everything I can and ask for nothing from him in return,'noblesse oblige', he won't try to annex anything and will work with me for a world of democracy and peace."Truman had followed the Allied progress of the war. George Lenczowski notes that, "despite the contrast between his modest background and the international glamour of his aristocratic predecessor, had the courage and resolution to reverse the policy that appeared to him naive and dangerous", "in contrast to the immediate ad hoc moves and solutions dictated by the demands of the war".
With the end of the war, the priority of allied unity was replaced with the challenge of the relationship between the two emerging superpowers. The two leading powers continued to sustain a cordial relationship to the public, but suspicions and distrust lingered between them. Truman was much more suspicious of the Communists than Roosevelt had been, he became suspicious of Soviet intentions under Stalin, he and his advisers saw Soviet actions in Eastern Europe as aggressive expansionism, incompatible with the agreements that Stalin had committed to at Yalta the previous February. In addition, Truman became aware of possible complications elsewhere when Stalin objected to Churchill's proposal for an early Allied withdrawal from Iran, ahead of the schedule agreed at the Tehran Conference; the Potsdam Conference was the only time. At the Yalta Conference France had been granted an occupation zone within Germany, France had been a participant in the Berlin Declaration, France was to be an equal member of the Allied Control Council.
At the insistence of the Americans, General de Gaulle was not invited to Potsdam, as he had too been denied representation at Yalta. Reasons for the omissions included the longstanding personal mutual antagonism between Roosevelt and De Gaulle, ongoing disputes over the French and American occupation zones and anticipated conflicts of interest over French Indochina. At the end of the conference, the three Heads of Government agreed on the following actions. All other issues were to be answered by the final peace conference to be called as soon as possible; the Allies issued a statement of aims of their occupation of Germany: demilitarization, democratization, decentralization and decartelization. Germany and Austria were each to be divided into four occupation zones, each capital and Vienna, was to be divided into four zones, it was agreed. All German annexations in Europe were to be reversed, including Sudetenland, Alsace-Lorraine and the westernmost parts of Poland. Germany's eastern border was to be shifted westwards to the Oder–Neisse line reducing Germany in size by 25% compared to its 1937 borders.
The territories east of the new border comprised East Prussia, West Prussia, two thirds of Pomerania. These areas were agricultural, with the exception of Upper Silesia, th
Surrender, in military terms, is the relinquishment of control over territory, fortifications, ships or armament to another power. A surrender may be accomplished peacefully, without fighting, or it may be the result of defeat in battle. A sovereign state may surrender following defeat in a war by signing a peace treaty or capitulation agreement. A battlefield surrender, either by individuals or when ordered by officers results in those surrendering becoming prisoners of war. Merriam-Webster defines surrender as "the action of yielding one's person or giving up the possession of something into the power of another", traces the etymology to the Middle English surrendre, from French sur- or sus-, suz "under" + rendre "to give back". A white flag or handkerchief is taken or intended as a signal of a desire to surrender, but in international law, it represents a desire for a parley that may or may not result in a formal surrender. A surrender will involve the handing over of weapons. Individual combatants can indicate a surrender by discarding weapons and raising their hands empty and open above their heads.
Flags and ensigns are hauled down or furled, ships' colors are struck. When the parties agree to terms, the surrender may be conditional; the leaders of the surrendering group negotiate privileges or compensation for the time and loss of life saved by the victor through the stopping of resistance. Alternatively, in a surrender at discretion, the victor makes no promises of treatment, unilaterally defines the treatment of the vanquished party. An early example of a military surrender is the defeat of Carthage by the Roman Empire at the end of the Second Punic War. Over time accepted laws and customs of war have been developed for such a situation, most of which are laid out in the Hague Convention of 1907 and the Geneva Conventions. A belligerent will agree to surrender unconditionally only if incapable of continuing hostilities. Traditionally, a surrender ceremony was accompanied by the honors of war; the Third Geneva Convention states that prisoners of war should not be abused. US Army policy, for example, requires that surrendered persons should be secured and safeguarded while being evacuated from the battlefield.
While not a formal military law, the Code of the US Fighting Force disallows surrender unless "all reasonable means of resistance exhausted and... certain death the only alternative": the Code states, "I will never surrender of my own free will. If in command, I will never surrender the members of my command while they still have the means to resist". False surrender is a type of perfidy in the context of war, it is a war crime under Protocol I of the Geneva Convention. False surrenders are used to draw the enemy out of cover to attack them off guard, but they may be used in larger operations such as during a siege. Accounts of false surrender can be found frequently throughout history. One of the more infamous examples was the alleged false surrender of British troops at Kilmichael, during the Irish War of Independence. Capitulation, an agreement in time of war for the surrender to a hostile armed force of a particular body of troops, a town or a territory. Debellatio occurs. No quarter occurs when a victor shows no clemency or mercy and refuses to spare the life of the vanquished when they surrender at discretion.
Under the laws of war, "it is forbidden... to declare that no quarter will be given". Unconditional surrender is a surrender without conditions, except for those provided by international law
The Soviet Union the Union of Soviet Socialist Republics, was a socialist state in Eurasia that existed from 1922 to 1991. Nominally a union of multiple national Soviet republics, its government and economy were centralized; the country was a one-party state, governed by the Communist Party with Moscow as its capital in its largest republic, the Russian Soviet Federative Socialist Republic. Other major urban centres were Leningrad, Minsk, Alma-Ata, Novosibirsk, it spanned over 10,000 kilometres east to west across 11 time zones, over 7,200 kilometres north to south. It had five climate zones: tundra, steppes and mountains; the Soviet Union had its roots in the 1917 October Revolution, when the Bolsheviks, led by Vladimir Lenin, overthrew the Russian Provisional Government which had replaced Tsar Nicholas II during World War I. In 1922, the Soviet Union was formed by a treaty which legalized the unification of the Russian, Transcaucasian and Byelorussian republics that had occurred from 1918. Following Lenin's death in 1924 and a brief power struggle, Joseph Stalin came to power in the mid-1920s.
Stalin committed the state's ideology to Marxism–Leninism and constructed a command economy which led to a period of rapid industrialization and collectivization. During his rule, political paranoia fermented and the Great Purge removed Stalin's opponents within and outside of the party via arbitrary arrests and persecutions of many people, resulting in at least 600,000 deaths. In 1933, a major famine struck the country. Before the start of World War II in 1939, the Soviets signed the Molotov–Ribbentrop Pact, agreeing to non-aggression with Nazi Germany, after which the USSR invaded Poland on 17 September 1939. In June 1941, Germany broke the pact and invaded the Soviet Union, opening the largest and bloodiest theatre of war in history. Soviet war casualties accounted for the highest proportion of the conflict in the effort of acquiring the upper hand over Axis forces at intense battles such as Stalingrad and Kursk; the territories overtaken by the Red Army became satellite states of the Soviet Union.
The post-war division of Europe into capitalist and communist halves would lead to increased tensions with the United States-led Western Bloc, known as the Cold War. Stalin died in 1953 and was succeeded by Nikita Khrushchev, who in 1956 denounced Stalin and began the de-Stalinization; the Cuban Missile Crisis occurred during Khrushchev's rule, among the many factors that led to his downfall in 1964. In the early 1970s, there was a brief détente of relations with the United States, but tensions resumed with the Soviet–Afghan War in 1979. In 1985, the last Soviet premier, Mikhail Gorbachev, sought to reform and liberalize the economy through his policies of glasnost and perestroika, which caused political instability. In 1989, Soviet satellite states in Eastern Europe overthrew their respective communist governments; as part of an attempt to prevent the country's dissolution due to rising nationalist and separatist movements, a referendum was held in March 1991, boycotted by some republics, that resulted in a majority of participating citizens voting in favor of preserving the union as a renewed federation.
Gorbachev's power was diminished after Russian President Boris Yeltsin's high-profile role in facing down a coup d'état attempted by Communist Party hardliners. In late 1991, Gorbachev resigned and the Supreme Soviet of the Soviet Union met and formally dissolved the Soviet Union; the remaining 12 constituent republics emerged as independent post-Soviet states, with the Russian Federation—formerly the Russian SFSR—assuming the Soviet Union's rights and obligations and being recognized as the successor state. The Soviet Union was a powerhouse of many significant technological achievements and innovations of the 20th century, including the world's first human-made satellite, the first humans in space and the first probe to land on another planet, Venus; the country had the largest standing military in the world. The Soviet Union was recognized as one of the five nuclear weapons states and possessed the largest stockpile of weapons of mass destruction, it was a founding permanent member of the United Nations Security Council as well as a member of the Organization for Security and Co-operation in Europe, the World Federation of Trade Unions and the leading member of the Council for Mutual Economic Assistance and the Warsaw Pact.
The word "Soviet" is derived from a Russian word сове́т meaning council, advice, harmony and all deriving from the proto-Slavic verbal stem of vět-iti, related to Slavic věst, English "wise", the root in "ad-vis-or", or the Dutch weten. The word sovietnik means "councillor". A number of organizations in Russian history were called "council". For example, in the Russian Empire the State Council, which functioned from 1810 to 1917, was referred to as a Council of Ministers after the revolt of 1905. During the Georgian Affair, Vladimir Lenin envisioned an expression of Great Russian ethnic chauvinism by Joseph Stalin and his supporters, calling for these nation-states to join Russia as semi-independent parts of a greater union, which he named as the Union of Soviet Republics of Europe and Asia. Stalin resisted the proposal, but accepted it, although with Lenin's agreement changed the name of the newly proposed sta
