I can give Bush a little slack when he said that islam is a religion of peace. He didn't want to declare war on a billion people after 9/11, and so he had to offer a face saving way out for muslims to join civilization, and cut the problem down to something manageable. As ISIS shows, they didn't take the offer.
In the last 14 years the offer has been reinterpreted into an excuse for doing nothing. Even that now is wearing thin. Nobody should be mimicking Bush today.
