Truthdig salutes Pa. Rep. John Murtha for his sustained leadership in demanding a pullout of U.S. troops out from Iraq. Particularly inspiring was his conduct during Thursday’s congressional debate over the war. A GOP congressman all but called Murtha a coward, and the 38-year Marine veteran thundered back a response that sent the congressman scurrying for cover. In doing so, Murtha again demonstrated the Republican fallacy of equating a call for withdrawal with weakness. It’s a lesson more Democrats could stand to learn.
