What did the Truman Doctrine Marshall Plan and NATO have in common?

The Truman Doctrine, Marshall Plan, and NATO were all key components of U.S. foreign policy during the early Cold War, aimed at containing the spread of communism and promoting stability in Europe. The Truman Doctrine established a commitment to support nations resisting communist influence, while the Marshall Plan provided economic aid to rebuild European economies and prevent communist takeover. NATO, formed in 1949, created a military alliance among Western nations to collectively defend against potential Soviet aggression. Together, these initiatives reflected the U.S. strategy of containment and support for democratic governments.
