Now even military leaders don't know why we invaded Iraq

Latest CNN headliner (emphasis mine):

U.S. officials rethink hopes for Iraq democracy

Nightmarish political realities in Baghdad are prompting American officials to curb their vision for democracy in Iraq. Instead, the officials now say they are willing to settle for a government that functions and can bring security.

Let me finish that thought for you:

"Wait, that's what they had before we invaded. Ok, now I remember: we also want a government that won't make weapons of mass destruction to use against the U.S. Wait, didn't we find out they already had that too? Well crap, what the hell are we doing here then?"
