What was one major difference in the way NATO and the Warsaw Pact were created?

NATO was created in 1949 as a collective defense alliance among the United States, Canada, and Western European countries, partly to contain the spread of communism. The Soviet Union formed the Warsaw Pact in 1955 to unite communist countries in Eastern Europe and strengthen their defense against NATO. Thus, the correct choice is “NATO was established to fight the spread of communism, while the Warsaw Pact was formed to protect communism.”
