The truth is that there were no lies involved:
Bush Lied is the Big Lie. It takes the controversy over one aspect of U.S. intelligence on Iraq's WMD -- the nuclear program question -- to argue that the whole WMD argument was bogus. That is, the president's accusers are guilty of the very sort of dishonest selectivity that they accuse Bush of using.
I expected that Saddam had chemical weapons based on the simple facts that Saddam used chemical weapons in the past, he failed to account for all the materials that he had to produce chemical weapons, and that he was obstructing the UN inspectors trying to find out what the true status was. I didn't expect either biological or nuclear weapons but was uncertain about their status given past disclosures of more progress than we believed.
I'm still waiting for version 5.0 about what happened to Saddam's WMD. And never forget that if Saddam was bluffing to hold the angry Iranians at bay, once freed of sanctions Saddam would have covered that bluff before he could be discovered.
Talk about an inconvenient truth.
