I came across the following in Paul Krugman's July 21st column:

As I wrote back in January 2003, this meant that the “Bush doctrine” of preventive war was, in practice, a plan to “talk trash and carry a small stick.” It was obvious even then that the administration was preparing to invade Iraq not because it posed a real threat, but because it looked like a soft target.

The message to North Korea, which really did have an active nuclear program, was clear: “The Bush administration,” I wrote, putting myself in Kim Jong Il’s shoes, “says you’re evil. It won’t offer you aid, even if you cancel your nuclear program, because that would be rewarding evil. It won’t even promise not to attack you, because it believes it has a mission to destroy evil regimes, whether or not they actually pose any threat to the U.S. But for all its belligerence, the Bush administration seems willing to confront only regimes that are militarily weak.” So “the best self-preservation strategy ... is to be dangerous.”

With a few modifications, the same logic applies to Iran. And it’s easier than ever for Iran to be dangerous, now that U.S. forces are bogged down in Iraq.

Would the current crisis on the Israel-Lebanon border have happened even if the Bush administration had actually concentrated on fighting terrorism, rather than using 9/11 as an excuse to pursue the crazies’ agenda? Nobody knows. But it’s clear that the United States would have more options, more ability to influence the situation, if Mr. Bush hadn’t squandered both the nation’s credibility and its military might on his war of choice.
