Answer: The Truman Doctrine
The Truman Doctrine was concerned especially about the threat of communism and totalitarianism as those "authoritarian powers."
The Truman Doctrine was first stated by President Harry Truman to Congress in 1947, saying: "It must be the policy of the United States to support free people who are resisting attempted subjugation by armed minorities or by outside pressures." Essentially, the Truman Doctrine pledged American effort elsewhere in the world to check the spread of communist and Soviet influence. The policy was first put into action in 1948 by providing economic support to Greece and Turkey to stave off communist movement in those countries.
The 1763 Treaty of Paris ended the major war known by Americans as the French and Indian War and by Canadians as the Seven Years' War / Guerre de Sept Ans, or by French-Canadians, La Guerre de la Conquête. It was signed by Great Britain, France and Spain, with Portugal in agreement. Preferring to keep Guadeloupe, France gave up Canada and all of its claims to territory east of the Mississippi River to Britain. With France out of North America this dramatically changed the European political scene on the continent.
