Eisenhower did nothing when the Soviet Union crushed the Hungarian revolution in 1956. Reagan skedaddled out of Lebanon after the Marine bombing and did nothing when the Soviets shot down that airliner over Korea. If you want to search for examples of Republicans who didn't react when the commies did something bad, there are a number of examples. Those were all tactical and strategic decisions made in the fight against communism.
Hear the liberal talking point comparing the JFK, the Bay of Pigs and Cuba to Eisenhower's inaction during the Hungarian revolution a lot. There was one huge difference: Soviet tanks were not going to roll through the Fulda gap into Key West Florida. Besides, had Ike acted, traitors in the Democrat party would have bitched and screamed.
No comparison between what you cite as the GOP being soft on communism and having a Soviet spy in your administration, knowing about it, and promoting him--as Truman did. Republicans were not the ones who gutted the CIA and FBI in the 1970s, Republicans were not the ones who squealed like stuck pigs when Reagan decided not to contain but to bust the Soviet Union.
Remember, Democrats passed the Boland Amendment, making it ILLEGAL to fight Soviet expansion in Central America.
What else do you need to know about the Rat party than that?
I still maintain that yesterdays Dems are different than todays. You simply can't cite a few examples of Truman's missteps early on in his presidency, and deny his Marshall Plan, support for loyalty oaths and other anti-communst measures, and his response to communist aggression in Korea. The same with Kennedy. To believe that the Dems have always been subversive leftists waiting for the chance to install communism is absurd. There is a Cult of Coulter on Free Republic. And let me state to her loyal fans even Coulter can be wrong, and I'll further state that I too am a fan of hers. But read Horowitz's comments about Coulter's book on his website. And try to keep an open mind about things.
