Isolationists seek to discredit warnings about the great dangers of a nuclear-armed Iran as “warmongers” or “neocons.” Yet history proves the opposite: Isolationism allowed Nazi Germany to arm and vastly expand its war machine, in violation of the Treaty of Versailles. In reality, isolationists are the most dangerous war-mongers. Their intent to keep the U.S. out of military conflict (short of a direct attack on the U.S. homeland), virtually ensures a catastrophic war.
