Although the two primary opponents in the Cold War were the United States and the Soviet Union, the conflict spread all over the world, with proxy battles fought in such places as Southeast Asia, Central America, and Africa during the second half of the 20th century. The most notable hot wars during that time were the Korean War (1950–1953), the Vietnam War (1959–1975), and the Soviet invasion of Afghanistan (1979–1988). However, a variety of other countries took their turns on center stage during the Cold War, including Angola, China, Cuba, Czechoslovakia, Nicaragua, and Poland. The Cold War also bore witness to the rise to prominence of such leaders as Fidel Castro and Lech Walesa.
