Perle was superb.
But did you catch it when he said the mistake in Iraq was not in going in but in carrying out an "occupation"...being an "occupying power", in which case the populace was bound to become disgruntled. I don't understand what Perle would have had us do. Have you heard anyone give a good alternative to our stay in Iraq, after we got there? I have not.
Note he didn't complain that we dismantled the Army or failed in reconstruction or keeping law and order, etc. He said we made a mistake by occupying Iraq, not by going in. Duh? What should we have done?
