To the best of my recollection, not his predictions (could be wrong on that, open to correction), rather regurgitation of DoD think tank predictions.
You could be right but never the less he went public in Newsweek and on the air with predictions of 50,000 dead. It brings into question his judgement on such matters. He served his country well and should be honored for that but he is not in the loop.
I trust Rumsfield, he is in the loop.
