Why? because we trusted lunatics?

So we went into a destructive, deadly debacle in Iraq because Saddam Hussien had WMD and was using them on his own people and torturing his own people to death.
Except; he didn't have them, and we've used them on his own people and, despite them having a very poor version of democracy, now Iraqi's are still being tortured to death.

Was it because we trusted in the paranoid delusions of lunatics?

How can we prevent the next mistake?
