WMD: Rummy's Monica Strategy
Clinton knew about his affair with Monica, and he knew that eventually everyone would know so, as everyone knows he leaked his confession a bit at a time. By the time he made his full confession everyone already knew, no one was surprised or shocked and he got off scot free. Everyone shrugged: well, that's just our Bill, dear old sleazy Bill. And it wasn't such a big deal really, was it?
Now Rummy is leaking his confession about those Weapons of Mass Distruction. From confident assertions that they're there, we just have to find them, to mini-confessions about possible miscalculation and bad information...eventually the full confession will be out and the hope is that by then no one will be surprised or shocked. Yes indeed we had no good reason to think that there were weapons of mass destruction in Iraq but we wanted to invade and it was a good excuse.
The difference is that Rummy got lots of people killed, spent millions and blew up Bagdad--a much bigger blow job than Bill's.
