The Bush doctrine, which flung open the doors to the catastrophe in Iraq, was such a fundamental aspect of the administration’s foreign policy that it staggers the imagination that we could have someone no further than a whisper away from the White House who doesn’t even know what it is.

You can’t imagine that John McCain or Barack Obama or Joe Biden or Hillary Clinton or Joe Lieberman would not know what the Bush doctrine is. But Sarah Palin? Absolutely clueless.

Ms. Palin’s problem is not that she was mayor of a small town or has only been in the Alaska governor’s office a short while. Her problem (and now ours) is that she is not well versed on the critical matters confronting the country at one of the most crucial turning points in its history.

The economy is in a tailspin. The financial sector is lurching about on rubbery legs. We’re mired in self-defeating energy policies. We’re at war. And we are still vulnerable to the very real threat of international terrorism.

With all of that and more being the case, how can it be a good idea to set in motion the possibility that Americans might wake up one morning to find that Sarah Palin is president?

I feel for Ms. Palin’s son who has been shipped off to the war in Iraq. But at his deployment ceremony, which was on the same day as the Charlie Gibson interview, Sept. 11, she told the audience of soldiers that they would be fighting “the enemies who planned and carried out and rejoiced in the death of thousands of Americans.”

Was she deliberately falsifying history, or does she still not know that Iraq and Saddam Hussein had nothing to do with the Sept. 11 attacks?
