I commend Professor Slaughter's decision to broach a difficult but still important subject. As Snowden and his predecessors have shown, US systemic primacy, and the determination expressed by successive Administrations to extend this primacy into the indefinite future by widening and deepening its overwhelming all-domain superiority, can only serve to gravely imprint profound collective insecurity among those at the receiving end of this dominance. As recent hacks initiated by both the NSA and its Five-Eyes partners, and others, show quite clearly, this is a game many can play. America can not logically emphasise its system-encompassing national interests on the one hand, and deny any rival (or even non-allied) state might have comparable interests on the other, and still expect good and predictable order to prevail without lethal enforcement. Obligations, like charity, usually begin at home. No?
