He's not an isolationist; he's just an anti-Semite. If he were an isolationists he would've opposed foreign aid to Hamas and not called for America to restrain Israel as regards Iraq. He believes in an interventionist foreign policy as long as the policy hurts or destroys the Jewish state.
He's not even a real conservative. He reveals in this article that he is a protectionist. So in what way is Pat a conservative? I actually applaud Bush for standing against protectionism.
