Who was the first North American leader to visit the Soviet Union?

The first North American leader to visit the Soviet Union was Pierre Trudeau, who served as Prime Minister of Canada. His visit took place in June 1971, during a time when relations between Canada and the Soviet Union were beginning to thaw amidst the Cold War tensions. Trudeau's approach was distinctive as he sought to engage with the Soviet leadership for diplomatic dialogue, which included discussions on various global issues and the policy of detente. This visit was significant not only because it marked a breakthrough in Canadian-Soviet relations but also because it represented a shift in how Western leaders approached relations with the Soviet Union, recognizing the importance of direct dialogue in international diplomacy.

Other leaders mentioned, like Lyndon B. Johnson, John F. Kennedy, and Richard Nixon, had their own critical interactions with the Soviet Union, but it was Trudeau's visit that was pioneering as the first by a North American head of government.
