I suspect your real problem isn't that we followed the herd, Jim, but that we've continued to reject the position of your president and his cabinet and have been shown, time after time, to have been correct in doing so.
There were no WMD. Now there is no evidence that those weapons were sent to Syria.
There was no connection between Saddam Hussein and 9-11.
There was no connection between Saddam Hussein and Osama bin Laden.
The invasion was illegal.
The use of napalm is illegal.
The use of depleted uranium is illegal.
The detention of prisoners not classed as POWs is illegal.
The torture of prisoners is illegal.
