"Reagan Was Right"

Ron Paul invokes a Republican icon in urging non-entanglement in the "irrationality" of Middle East politics. Notice that Paul gets a smattering of applause before the Fox News questioner squelches Paul's point about blowback and puts words in his mouth about 9/11. I stand by my judgment of the exchange last night. Does Giuliani believe that "blowback" doesn't exist? How does it factor into his foreign policy thinking?
