There are 3 Kinds of Liars:

Liars, damned liars and George W. Bush. Given the National Intelligence Estimate on Iran (the person who released this report deserves a Medal of Freedom, by the way) and Bush's presser this morning, not to mention his past assertions that Iran was busily developing nuclear weapons despite knowing damned well they weren't, how can anyone believe him again. It appears WWIII, Armageddon or whatever you want to call it is on hold. Gog and Magog aren't cooperating. So unless Bush contrives to sink one of our carriers and foists blame on Ahmedinijad, the Big One is off for now.

Liar, unfortunately, isn't the best word for Bush given this turn of events. He beat the drum of war, knowing for months that the drum was hollow. His attempt to start a second war on false pretenses leave only one word to describe Bush and his cabal:

Warmonger.
