Some English grammar corrections; What "were" the countries ----- not what "where". Who was the leader of the USSR after Stalin? instead of the question used. Greece had a civil war from 1946 - 1949 between the communists and the greek army with over 100, 000 civilian deaths. The US support for Greece as expressed by the Truman Doctrine was an early indication of the Cold War. Thus, the proxy war answer doesn't make any sense.
