The best answer is prevent the spread of communism outside of Eastern Europe.

The “containment” concept was established by George F. Kennan, a brilliant  diplomat and political analyst stationed at the U.S. embassy in Moscow. He insisted that a third world war with  the Soviets was unlikely as long as America adopted policies to keep them  contained. As he wrote, “the main element of any United States policy toward  the Soviet Union must be that of a long-term, patient but firm and vigilant  containment of Russian expansive tendencies.”
