Yes, we knew McCain had an ego. We never quite appreciated how vast it was. Yes, Obama is inexperienced in foreign policy. But at least he has thought seriously about it. Do you really believe that Sarah Palin understands the distinctions between Shia and Sunni, has an opinion about the future of Pakistan, has a view of how to exploit rifts within Tehran's leadership, knows about the tricky task of securing loose nuclear weapons? Does anyone even know if she has ever expressed a view on these matters? Here's a bleg: can anyone direct me to any statement she has ever made about foreign policy?

The biggest secret of the Bush administration is that they were never serious about national security. Serious leaders do not fabricate intelligence through torture methods borrowed from the Communist Chinese. Serious leaders do not invade foreign countries on dubious intelligence with no plan for an occupation. Serious leaders do not try to manipulate detainee policy for electroal purposes. Serious leaders do not engage in moronic talk of victory or surrender five years after removing a regime.

And now we know something about McCain's promise: he takes all this even less seriously than Bush.
