I don't think so. He's too old to be afraid of anything anymore :) IMO, he's just a naive isolationist. Which is really too bad because a lot of his domestic positions are spot on. He's best when he's channeling von Mises and Hayek, and discussing monetary policy and Austrian Business-Cycle Theory.
Perhaps. But Rep. Paul was saying (essentially) that Iran was too big for us to take on, and that bothered me. They’ll be a lot “bigger”, and bolder, when they have nukes.
