"The question serious supporters of a real war on terror must now ask is: will continuing the fight in Iraq help reverse this trend or cement it for decades to come? Is the war making us less secure and the world much less safe? Would withdrawal or continued engagement makes things better? At the very least, it seems to me, this question should be on the table in the Iraq debate. And yet the Republicans - with the exception of Ron Paul - don't even want to talk about it. Until they do, they are not a party serious about national security."
