What Obama is pursing in Iran and Cuba isn’t peace.
Republicans don’t talk about peace as much as they used to, or as much as they should. President Dwight Eisenhower, whose unflashy élan masked the difficulty and danger of the serial crises he managed, put “waging peace” at the center of his agenda, even as circumstances obliged him to wage war. President Reagan famously described his agenda as “peace through strength,” a formulation that goes back at least as far as Hadrian. Since then, Republicans have been relatively good on the “strength” part — they have rarely encountered a line item on the military budget that did not enrapture them — but, with the notable exception of Senator Rand Paul, the “peace” side of the equation is something of a stepchild for the Right.
Democratic presidents have more enthusiastically embraced the role of “peacemaker,” and by “role” I mean just that: Democratic peacemaking has amounted to very little more than political theater. From Carter to Clinton to Obama, the Democrats have not been peace-makers but peace-fakers.
