If terror groups are to be defeated, it is national governments that will have to do so. In nations like India, governments will have to call on the patriotism of citizens to fight the terrorists. In a nation like Pakistan, the government will have to be persuaded to deal with those in their midst who are complicit.

In any case, open-seat presidential elections like 2008 just are different in character from incumbent reelects, and I think that's the most important thing about this election - is that once there's an incumbent running for reelection, most of the debate is about, "Has he [Barack Obama] done a good job?"
