And that Empire of his would be an easier enemy for any rebels and Jedi remnants, because for all his power Anakin lacks Palpatine's calculating mind that made his Empire so effective and efficient. Anakin's Empire would be all "Attack! Attack! Attack!", with little if any strategical planning, political management and security.
I have to disagree with that. Though I don't think his Empire would be nearly as organized, I don't feel that there wouldn't be any strategy. He WAS a war general after all. He wouldn't be as successful as Palpatine but I feel he could hold his own.
