When you are armed and powerful; when vendetta drives policy; when concern for the never-satisfied-lobbyists becomes a part of inviolable cluster of priorities, we end up doing very unconscionable things. Problem is, times change. The U.S is not going to be #1 in global-death-delivery technology forever. This is the time to be most supportive of international law and basic human decency. We have come around, inevitably, to trade with China and Vietnam, Russia and former Soviet states. We trade with former enemies, Japan, Germany and others. It’s exhausting searching for moral justification for the Cuba embargo.
