I think Bush does likely bear some responsibility for the polarization of opinion.
I think some of his speeches have been very stark, engendering suspicion in those already inclined to think the worst of him.
At the same time, it is entirely possible that if Bush had taken his eye of his goals:
Ending the 12 years of Iraqi game playing and support of anti-American sentiment,
Defending American interests as plainly expressed for many years,
Planning what is increasingly looking likely to be a brilliant war against saddam,
Then maybe we would not be crushing AlQaeda and saddam as we are.
Whatever stylistic weaknesses Bush has, the deliberate betrayal of the UN by france and chirac was their own diong and the accountability for it will be on their heads.
