> Last few decades of USA foreign policy show it more clearly than any reasonable person should require. I think the last few decades of USA foreign policy show that meaningful change takes time - a long time. We're still protecting South Korea, Germany, and Japan. I would consider all of those successful exercises in "nation building" as once totalitarian nations have built stable democracies. But in Vietnam, Iraq, and Afghanistan, we simply weren't willing to stay long enough to protect the new democracies from their enemies.
