>> I seriously doubt that she believes it enough to try to act on it in real life
I doubt it as well. I think Sarah Palin will make not only an excellent domestic POTUS, but one of the best foreign policy leaders and CinCs we have ever had. She has principles, she believes America deserves its role as premier sovereign nation, and she is cool-headed, smart, and a fast learner too.
Sadly, I can see the left and the Republican establishment using this issue you bring up to paint her as an Armageddon nutjob a la Ahmanijihad. I trust she is anticipating that slander and has a plan ready to counteract it.
I strongly disagree. She's nowhere near ready for the job. Good intentions and nice principles are important, but not nearly enough.
