“Since morality and social order cannot be imposed by foreign attacks and aggressive wars to alter governments and entire societies, what these American intrusions have caused is death and destruction in one country after another, plus hatred and revenge visited upon the invaders. What Americans now recognize, if only by gut instinct, is that the war policy has backfired. The global war on terror has backfired. Interventionism has backfired. America has done wrong, morally and pragmatically. Americans are coming to recognize this while their leaders are still caught up in their false notions that power and their power in particular can remake the world for the better.”
