Did I say that Bush lied? It's a dumb canard anyways.
More accurately they found degraded chemical weapons which didn't match the pre-war hype, quietly hushed everything up, and used the fleeting success of the "Surge" to run the clock out until Obama could be inaugurated. Which ironically is kind of what Obama is doing currently in Afghanistan.
Doogsinparadise pere still insists that the chemical stocks were smuggled into Syria in 2003, which is probably a better argument then that this stuff means anything.
As for the efficacy of the Iraq War, well you've just got to look at what has happened there in the last decade. One civil war following the invasion, and then an effective sectarian partition with the south under massive Iranian influence and the north under the tyranny of ISIS. Saddam was a cuntbag, but by 2003 he was hardly worse than any of the other despots that we've coddled and propped up over the last few decades. The neocons let their emotions get the best of them--which we saw again in Libya--and look what happened. Have American interests been advanced in the Middle East? Fuck no.
