“From our founding we have made these kinds of moral demands of our soldiers. It starts with the oath they swear to support and defend the Constitution, an oath made not to a flag, or to a piece of ground, or to an ethnically distinct people, but to a set of principles established in our founding documents. An oath that demands a commitment to democracy, to liberty, to the rule of law and to the self-evident equality of all men. The Marines I knew fought, and some of them died, for these principles.”
