This article has been around for a while (since long before I migrated to the blogosphere) but it's worthwhile linking it again. The gist is:
The official story on Iraq has never made sense. The connection that the Bush administration has tried to draw between Iraq and al-Qaida has always seemed contrived and artificial. In fact, it was hard to believe that smart people in the Bush administration would start a major war based on such flimsy evidence.
This war, should it come, is intended to mark the official emergence of the United States as a full-fledged global empire, seizing sole responsibility and authority as planetary policeman. It would be the culmination of a plan 10 years or more in the making, carried out by those who believe the United States must seize the opportunity for global domination, even if it means becoming the "American imperialists" that our enemies always claimed we were.

Note the date Bookman wrote his article - 29 September 02 - long before the war aims started morphing from weapons of mass destruction to regime change to violation of Resolution 1441 to violation of Resolutions 678 and 687 to democratization of the Middle East.
