Answer:
The Atlantic Charter was an agreement between the United States and Great Britain that eventually served as a model for the United Nations.
Explanation:
The Atlantic Charter was a diplomatic act signed by US President Franklin D. Roosevelt and British Prime Minister Winston Churchill on August 14, 1941 aboard the battleship Prince of Wales anchored in the Terranova Bay, among the Allied powers, which foresaw the enunciation of some principles for the future world order: prohibition of territorial expansions, internal and external self-determination, democracy, peace understood as freedom from fear and want, renunciation of the use of force, and a general security system that would allow disarmament. It resumed Wilson's "Fourteen Points" and affirmed the freedom of trade and navigation and the right of peoples to live "[...] free from fear and want". It was the seed of the birth of the UN and was consistent with the Stimson Doctrine, a declaration of general rejection of the territorial acquisitions obtained with the use of force, and with the Welles Declaration, issued in the particular case of the Soviet occupation of the Baltic republics.
In a 1946 speech, British Prime Minister Winston Churchill said an iron curtain had fallen across the continent of Europe.
