This seems a fair assessment from Oliver Kamm:
For all Bush’s verbal infelicity, diplomatic brusqueness, negligence in planning for post-Saddam Iraq, and insouciance regarding standards of due process when prosecuting the war on terror, the world is a safer place for the influence he has exercised.
When Bush ran for president in 2000 he was an isolationist advocate of scaling back America’s overseas commitments. But after 9/11, he was right in not interpreting the attack as confirmation that America was stirring up trouble for itself. The theocratic barbarism responsible for the attack on the Twin Towers was driven not by what America and its allies had done, but by what we represented. In the words of Osama bin Laden, illegitimately appropriating for himself the mantel of Islam, “every Muslim, the minute he can start differentiating, carries hate toward Americans, Jew, and Christians”.
The most fundamental decision in western security policy in the past seven years has not been the overthrow of Saddam Hussein. It has been the recognition that the most voluble adversaries of western society are not merely a criminal subculture, and still less an incipient liberation movement. Rather, they are a reactionary, millenarian and atavistic force with whom accommodation is impossible as well as intensely undesirable.
