No we didn't. Russia wasn't the only communist nation. China is communist. We had our asses kicked in Korea and Vietnam fighting proxy wars with Russia and China. Korea, which was called a "police action" ended in a ceasefire that remains in place today. In Vietnam, we left the country to the commies. Now we do business with communist countries. And Cuba after all these years is still communist. Spain's Prime Minister Sanchez is a communist/socialist. And we've got commies in our own country, because while we were fighting the spread of communism overseas, we took our eye off the ball at home, and communism snuck into our education, judicial and political system here.
We were lucky not to lose Italy and France to the Communists after WWII.
The Communists were well on their way in France, already eliminating opponents by accusing them of being collaborators, before DeGaulle put a stop to it.
