Show me a man who never speaks a mistaken word...
...and I'll show you a man who never utters a sound.
So Wretchard was wrong. He mistook the change in the nature of the conflict for the end of the war in Iraq. I don't think this error necessarily invalidates or undermines his commentary about the conflict in Iraq now.
As for the link you provided, I'm not sure, but I think it's possible that Wretchard may have known this man personally. He offers no link to a news story, as he often does.
