Ta-Nehisi Coates has an excellent post-mortem on the excremental Michael Kelly,
who wasn't so much a cheerleader for the invasion of Iraq but a pitbull, rabidly slavering his militaristic fantasies on anyone with spitting distance.
His apologists will claim he was only wrong in hindsight, but that's not true. As the excepts quoted by Coates illustrate, Kelly wasn't reporting facts, he was seeking to make things true by wishing them to be true (and doing so in a truly obnoxious manner).
Kelly was wretched. He was vile. He was contemptible.
And he was one of a rare breed to whom the phrase "hoist with his own petard" applies literally.
