A nuclear weapon of some dimension, whether it's actually a nuclear weapon, or a dirty bomb, or some kind of radiological device. Yes, I think it's probably a near thing.

But more important, I think, is the criticism bin Laden has made publicly over the past 10 years that Muslim governments cannot even protect their own people. And more than that, they'll often collude with the infidels. And if you recall, the initial reaction of the Arab league was to criticize Hezbollah and damn Hezbollah for the war. And they eventually had to turn 180degrees and support Hezbollah.

I think you can take the recent war in Lebanon as a very good example of how this plays. The Americans and their allies clearly stood back - clearly in the eyes of Muslims - and basically said to the Israelis, "Do what you need to do, and we'll hold the ring for you and not call a cease-fire." That perception in the Muslim world very much played to the anti-American sentiment.

If the Americans attack Iran for the first time in 1,400 years, we may unite Sunnis and Shias against us. So I guess there is room for accomplishment everywhere.

Bin Laden does reprehensible activities, and we should surely take care of that by killing him as soon as we can. But he's not an irrational man. He's a very worthy enemy. He's an enemy to worry about.

Our relationship with Israel is another reason we're being attacked. But an American politician - whether Muslim or not - who criticizes Israel as a martyrdom operation in American politics cannot survive as an official or as a politician.

I think clearly Europe has a lot to worry about. When I was working at the CIA - and I always worked with a lot of European services - they always were very condescending toward the United States, saying that we are so racist vis-à-vis blacks and other people.
