France is one of the five "Nuclear Weapons States" under the Treaty on the Non-Proliferation of Nuclear Weapons, but is not known to possess or develop any chemical or biological weapons. France is the only member of the European Union to possess independent (non-NATO) nuclear weapons. France was the fourth country to test an independently developed nuclear weapon, doing so in 1960 under the government of Charles de Gaulle. The French military is currently thought to retain a weapons stockpile of around 300 operational (deployed) nuclear warheads, making it the fourth-largest in the world, speaking in terms of warheads, not megatons. The weapons are part of the national Force de frappe, developed in the late 1950s and 1960s to give France the ability to distance itself from NATO while having a means of nuclear deterrence under sovereign control.

Charles André Joseph Marie de Gaulle was a French army officer and statesman who led the Free French Forces against Nazi Germany in World War II and chaired the Provisional Government of the French Republic from 1944 to 1946 to restore democracy in France. In 1958, amid the Algerian War, he came out of retirement when appointed Prime Minister by President René Coty. He rewrote the Constitution of France and founded the Fifth Republic after approval by referendum. He was elected President of France later that year, a position he held until his resignation in 1969.
