Our security depends on having good relationships with our allies. Donald Trump mainly shows contempt for them.

I don't know of a single instance of these Arab freedom fighters holding up pictures of bin Laden. I know many instances of them displaying American flags in Benghazi or painting 'Facebook' on their foreheads in Cairo. The idea of freedom . . . is absolutely contradictory to what bin Laden stood for, which was . . . taking Muslims back to some medieval theocracy and encouraging people to die not for freedom but to go to paradise and to kill innocent people along the way. The contrast is really striking.
