The policy that was central to the foreign policy of every president from Truman through Johnson is containment. Containment was the strategy employed by the United States during the Cold War to prevent the spread of communism, particularly by the Soviet Union. It aimed to stop the influence and expansion of communism into other countries.
Here's why containment was central to their foreign policy:
1. **Truman Doctrine**: President Truman's doctrine established the basis for containment by providing aid to Greece and Turkey to prevent them from falling to communist influence.
2. **Marshall Plan**: This plan, proposed by Secretary of State George Marshall, aimed to help rebuild European nations post-World War II, thus preventing economic instability that could lead to communist takeovers.
3. **NATO**: The establishment of the North Atlantic Treaty Organization was a key part of containment, as it formed a military alliance to counter Soviet aggression in Europe.
4. **Korean War**: During Truman's presidency, the U.S. intervened in the Korean War to prevent the spread of communism into South Korea, showcasing the implementation of containment.
Overall, containment was a fundamental aspect of U.S. foreign policy during the Cold War era, guiding actions to prevent the expansion of communism globally.
