Why did helen gahagan douglas oppose truman's plan for dealing with the crisis in greece?

Helen Gahagan Douglas wanted the United States to work through the United Nations to address the Greek crisis.

Helen Gahagan Douglas was one of very few women elected to Congress in the 1940s.  She served as representative of California's 14th District from 1945 to 1951.  After a communist revolution threatened the Greek government and a civil war broke out in 1946, President Truman announced what became known as the Truman Doctrine of intervention to help those threatened by communism.  In a March, 1947, in an address to Congress, Truman said:  "I believe it must be the policy of the United States to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures. I believe that we must assist free peoples to work out their own destinies in their own way. I believe that our help should be primarily through economic and financial aid which is essential to economic stability and orderly political processes."

Douglas was more inclined to pursue peaceful relations with the USSR and its allies than to support strong anti-communism measures.  She had said she supported the Marshall Plan in Europe because of decency rather than because of the Cold War.  She did not see Truman's plans for intervention in Greece in that same category, but mostly just a Cold War battle.
