In Steve Burnap's blog post entitled Infamy he writes

I've been opposed to the Iraq war since the beginning, but until this, I didn't feel disgust.

And that makes me sad. There are only villians here. Villians who have made the US no better than Saddam Hussein. We got into this war with lies, but even if there were no WMDs and no Al Qaeda connection, we could say "well, at lest we got rid of a tyrant". Now all we can say is that we've replaced a tyrant.

I share the exact same sentiments. The Iraq War has hit every worst case scenario I could have come up with; no weapons of mass destruction, no concrete ties to Al Qaeda shown, militant resistance from members of the local populace, and US troops actively violating the Geneva Convention. The funny thing is that polls show that 44 per cent of people polled in the US think the war is worthwhile.  Sad.
