It's conventional wisdom that the Iraq War was a disaster, and on a certain level that's true, but not for the reason most people think.
In the 11 years since the U.S. invasion, Iraq went from a brutal dictatorship to a fledgling democracy brimming with hope to an unstable state overrun by a terrorist cabal - not because the U.S. invaded, but because the politics of the invasion and the war became so absurd in the United States. The politics led to insane policy decisions in Washington, all based on the set-in-hard political narrative that fighting in Iraq is the most horrible thing America can possibly be involved with.
