Sarah Palin's reputation survived her interview with ABC News' Charlie Gibson.

The same cannot be said for Charlie Gibson.

On my radio show last week, I twice defended Barack Obama. Once, against those conservatives who took a comment made by Obama in an interview with George Stephanopoulos out of context and suggested that Obama had inadvertently admitted he was a Muslim. And again, when I contended that Obama did not imply that Palin was a pig in his now famous "lipstick on a pig" reference.

I mention this only because I want to assume that people of good will on both sides can still be honest about what transpires politically. And in this instance what transpired was that Gibson intended to humiliate Palin.

It wasn't even subtle. Virtually everything Gibson did and virtually every question he posed was designed to trap, or trick, or demean Gov. Palin. There are views of his face that so reek of contempt that anyone shown photos of his look would immediately identify it as contemptuous.

But one series of questions, in particular, blew any cover of impartiality and revealed Gibson's aim to humiliate Palin.

GIBSON: Do you agree with the Bush doctrine?

PALIN: In what respect, Charlie?

GIBSON: The Bush -- well, what do you -- what do you interpret it to be?

PALIN: His worldview?

GIBSON: No, the Bush doctrine, enunciated September 2002, before the Iraq war.

When he asked Palin whether she agreed with the Bush Doctrine without defining it, he gave the game away. He lost any pretense of fairness. Asking the same unanswerable question three times had one purpose -- to humiliate the woman. That was not merely partisan. It was mean.

I couldn't answer it -- and I have been steeped in international affairs since I was a Fellow at the Columbia University School of International Affairs in the 1970s. I have since been to 82 countries, and have lectured in Russian in Russia and in Hebrew in Israel. Most Americans would consider a candidate for national office who had such a resume qualified as regards international relations. Yet I had no clue how to answer Gibson's question.

I had no clue because there is no right answer. There are at least four doctrines that are called "Bush Doctrine," which means that there is no "Bush Doctrine." It is a term bereft of meaning, as became abundantly clear when Gibson finally explained what he was referring to: Continued...
