I liked this commentary a lot. Here's a good excerpt:

Bush wasn't strong enough to sustain the resolve necessary to hammer out alternatives to the crude solution of war. He wasn't strong enough to persuade others to his point of view. His diplomatic skills and his political instincts have been so weak that he managed to squander with breathtaking speed the global goodwill toward the United States after the attacks of Sept. 11. He managed even to fracture a patriotic American population that had set aside its differences to pull together after Sept. 11. We had rallied to him, even those of us who disagreed with his politics. But he didn't have the leadership to marshal that patriotism into a thoughtful, unified plan of action.
