We had to fill the post war vacuum in Europe, but the real enemy was right here among us.
For all his faults, McCarthy tried to tell us. 50 years later, when many of the relevant documents were unclassified, a researcher found that in fact there were people throughout the State Dept and the DOD who weren't just communist sympathizers, but who were on the payroll of Stalin.The most notable was a military attache to China. During WWII he would reverse the action reports about Mao's and Kai-shek efforts to fight the Japanese. He would report that Mao's army bravely battled against the Japanese, suffering many loses and that Kai-shek's people hid in caves like cowards. IN FACT it was just the opposite. This influenced congress and the DOD as to where to send military supplies. It wasn't until closer to the end of WWII another State Dept official realized what was happening, remove the attache and started sending corrected reports. BUT OF COURSE this was all CLASSIFIED until the late '90's.
