Okay, here's the question I would ask, if I wanted to see just how much about international diplomacy she actually knows:
"Governor Palin, what is your view on our diplomatic relations with Taiwan? Would you, as President, support their application to join the UN? Do you feel we should more formalize our relationship with them as another nation?"
Answer "Yes" to either of the last two questions, and you've got a serious diplomatic incident with the People's Republic of China. =)
I mean, she just said she'd go to war with Russia if they invade Georgia or the Ukraine, let's give her a REAL loaded question and watch what happens.
