In the exerpts she certainly looked nervous at best. As for this Bush Doctrine business, in fairness the term wasn't coined by Bush but by the media and was never an official name for that specific policy. The press has in fact refered to the 'Bush pre-emptive strike doctrine' of late when refering to that policy. I wouldn't crucify her on that one but she certainly needs to do a lot more homework on foreign policy or she will get roasted. Her comment on war with Russia was poorly worded. She recovered afterward by clarifying we could use sanctions, etc, but she allowed the interviewer to manuver her into making a dumb comment. She could have said, "The US and our NATO allies would respond appropriately..." or some such vagary.
