““It is of the nature of war to increase the executive at the expense of legislative authority," the Federalist tell us. And modern commanders in chief tend to reflexively invoke the war metaphor when the public demands that they take action to solve the emergency of the month, real or imagined. "War is the health of the state," Randolph Bourne's famous aphorism has it, but Bourne could just as easily written that "war is the health of the presidency." Throughout American history, virtually every major advance in executive power has come during a war or warlike crisis. Convince the public that we are at war, and constitutional barriers to actions fall, as power flows to the commander in chief. Little wonder, then, that confronted with impossible expectations, the modern president tends to recast social and economic problems in military terms: war on crime, war on drugs, war on poverty. Martial rhetoric often ushers in domestic militarism, as presidents push to employ standing armies at home, to fight drug trafficking, terrorism, or natural disasters. And when the president raises the battle cry, he can usually count on substantial numbers of American opinion leaders to cheer him on.””
