Why are Henry Kissinger, George Shultz, William Perry, and Sam Nunn writing opinion pieces in the Wall Street Journal calling for the abolition of nuclear weapons? Keep in mind, these four people are not just major defense hawks. People like Kissinger helped push through the single most dangerous and destabilizing innovation in nuclear weaponry, the arming of missiles with multiple warheads. All four have supported every conflict the United States has engaged in since World War II, all have enthusiastically supported nuclear weapons, and none has suddenly gone kumbaya on us.
