Gov. Rick Perry, R-Texas, came down firmly on the hawkish side of the Republican national security debate Saturday, saying "isolationist" figures like Sen. Rand Paul, R-Ky., are "blind" to the threat posed by terrorism. "I can understand the emotions behind isolationism," Perry wrote in an op-ed for The Washington Post. "Many people are tired of war, and the urge to pull back is a natural, human reaction. Unfortunately, we live in a world where isolationist policies would only endanger our national security even further."
