The United States supported its allies in the Cold War in many ways. One way was with economic aid. The United States provided economic assistance to countries that were threatened by communism. We understood that a country with a strong economy was less likely to become communist. Thus, we gave economic aid to Greece and Turkey immediately after World War II ended to help them to remain non-communist. We provided economic aid to South Korea and South Vietnam for the same reasons. We also offered economic aid to any Western European country that wanted it after World War II ended with the Marshall Plan. We didn't want to be accused of only offering help to non-communist countries. Thus, the Marshall Plan offered aid to communist and non-communist countries. Of course, the Soviet Union wouldn't let any nations in its communist alliance, the Warsaw Pact, accept this aid. As a result, the aid went to non-communist countries, as well.
Another example of how we helped our allies was with military assistance. We gave advice and weapons to South Korea and South Vietnam. We also provided troops to these countries in their fight against the spread of communism. We helped West Germany and West Berlin stay non-communist by providing supplies, weapons, and troops to keep communism from spreading to these areas.
We also have supported our allies politically. We have worked with the United Nations to stop the spread of communism. We engaged the United Nations in the struggle in Korea. We have protected countries by telling the Soviet Union, in the Cuban Missile Crisis, that an attack on a Latin American country would be viewed as an attack on the United States. There are several ways we have supported our allies in the Cold War.
