Here's Peter Whener at The Wall Street Journal:
Iraqis can participate in three historic elections, pass the most liberal constitution in the Arab world, and form a unity government despite terrorist attacks and provocations. Yet for some critics of the president, these are minor matters. Like swallows to Capistrano, they keep returning to the same allegations--the president misled the country in order to justify the Iraq war; his administration pressured intelligence agencies to bias their judgments; Saddam Hussein turned out to be no threat since he didn't possess weapons of mass destruction; and helping democracy take root in the Middle East was a postwar rationalization. The problem with these charges is that they are false and can be shown to be so--and yet people continue to believe, and spread, them. Let me examine each in turn...
Which he proceeds to do. In the process he demonstrates how irresponsible, perhaps even dishonest but certainly reckless, many of his critics are. He closes with this:
These, then, are the urban legends we must counter, else falsehoods become conventional wisdom. And what a strange world it is: For many antiwar critics, the president is faulted for the war, and he, not the former dictator of Iraq, inspires rage. The liberator rather than the oppressor provokes hatred. It is as if we have stepped through the political looking glass, into a world turned upside down and inside out.
It is indeed strange to hear people still today - when so much evidence of Saddam's complicity with terrorists has been unearthed and so many good reasons have been adduced for assuming that Saddam was working on WMD - it is indeed strange to see people clinging tenaciously to the myth that Bush lied about these things. I suppose there are psychological reasons for the tightness with which Bush's opponents grasp these thin reeds. To admit that they were completely and utterly wrong in their assessment of the president would be so devastating to their ego and to their credibility that they cannot bring themselves to do it.
They'd rather ignore the evidence and continue to impugn the president's character than to face up to the fact that they have been miserably and detestably irresponsible and wrong. Professing themselves to be wise they prefer nevertheless to look like fools rather than admit their error.
