John Dean, who should know a thing or two about such matters, has written that if it turns out there are no WMDs in Iraq, then G.W. is guilty of “the first potential scandal I have seen that could make Watergate pale by comparison.” Interestingly, he follows the format, sort of, laid down in the noted blog-post by billmon.
Coincidentally, a Pentagon report from September 2002 has made its way into public view, and it uses much more equivocal language about the existence of WMDs in Iraq than the administration. Never mind reports that the intelligence on WMDs was cooked.
Given the current makeup of Congress, it isn’t likely that anything G.W. does would result in impeachment proceedings. But it’s still interesting to hear his perspective.
