McCarthy underestimated the extent of Communist infiltration. He was smeared by the pro Communist main stream media. They, people like Mika Brzezinski, believe it is their job to tell us what to think. In the early 40s they convinced Americans that Joseph Stalin, the second greatest mass murderer after Mao, was a great humanitarian. Yes, The hysteria was another leftist creation. There is an American professor, Jeffrey Olick, who has written a book about Senator McCarthys work on the House Un-American Activities Committee. Is it any wonder why graduates are so uneducated? This was repeated by that great historian Bill OReily. Fortunately he was corrected by Ann Coulter. Our modern world is a creation of Communists from the Roosevelt administration. The World Bank and the International Monetary Fund are the creation of Harry Dexter White, a Soviet agent, in the Treasury. He was also the author of the Morgenthau Plan that nearly caused western Europe to go Communist.
