If you follow the Democrats' criticism since 9/11, you may have noticed two constant properties of that criticism: The visceral hatred for all things conservative and the absence of any specific proposals for how the war should be fought. All we've gotten so far is "well, I wouldn't have done that!" The closest John Kerry has been to a specific proposal is when he asserted his approach to be more "sensitive" and "nuanced" than George Bush's low-brow global war on terror.
What does John Kerry mean by a sensitive and nuanced war on terror? It is the policy we followed for the 50 years preceding 9/11. He thinks we are not at war and terrorism is a legal/diplomatic problem. The implication is we should pursue individual terrorists through diplomacy and in the courts, and if they hide in countries that use terrorism as an extension of their foreign policy, oh well, we just can't get them extradited.
