Final answer:
The phrase 'Atlantic Charter' was coined by Winston Churchill to describe the U.S.-England alliance, outlining post-WWII goals including self-determination and disarmament. The alliance played a foundational role in the postwar world and later Cold War tensions.
Step-by-step explanation:
The two-word phrase coined by Winston Churchill in 1946 to describe the diplomatic alliance between the U.S. and England is the "Atlantic Charter." This charter was an essential blueprint for Anglo-American cooperation during World War II and outlined the goals and objectives for the world after the war. It was negotiated by British Prime Minister Winston Churchill and U.S. President Franklin Roosevelt in August 1941 and proclaimed principles such as the right of self-determination, self-government restoration, freedom of the seas, and the reduction of trade barriers. Notably, it also called for postwar disarmament and renounced the use of force as a means of settling international disputes.
Churchill's speech in Fulton, Missouri, famously highlighted the postwar division of Europe, referring to an "iron curtain" which reflected growing tensions that would eventually lead to the American-Soviet Conflict during the Cold War era.
