She’s going to learn national security at the foot of the master for the next four years, and most doctors think that he’ll be around at least that longHow reassuring.
One other point that should be made about the lack of experience on the national scale: this isn't just about national security but about her ability to take advice and act accordingly. Regardless of whether you're physically in Washington, involvement in national politics brings with it a certain awareness of just how reliable the host of think-tank 'experts' are. You get to know which ones are just partisan hacks who have a knee-jerk response to whatever you say or do, and which ones actually think about the situation, potential ramifications, and the best course of action guided by an honest assessment. Palin isn't involved in national politics, and by most accounts wasn't even interested until she was tapped by McCain. She has no idea who in Washington will tell her 'yes' or 'no' just because she's a Republican, and who will actually try to give her good advice guided by the facts. Even if her intentions are noble, she risks surrounding herself with idealogical zealots who only care about pushing their own agenda, facts be damned, and she'll end up implementing that agenda. And we all know how that's played out in the past.
