This is quite interesting, though it does proceed on the assumption that Trump actually means what he says, but who really knows?  But Mearsheimer is plainly correct that Hillary Clinton is a "super hawk" with a record of terrible judgment on foreign policy matters.  Mearsheimer clearly likes that he hears Trump as moving away from the "liberal imperialism" of both the Republicans and Democrats, of which, of course, Mearsheimer himself is a critic (though, needless to say, a more nuanced one than Trump!).
