The safety and survival of humanity depend on international efforts to avoid any use of nuclear weapons, either in warfare or in terrorism. To persuade other nations to join us in these efforts, the United States should lead the way as outlined in your editorial.
Ultimately, the goal should be to declare that nuclear weapons should never be used and should be abolished. As President Obama has said, this is a future goal, but right now, the United States can declare that the sole purpose of having nuclear weapons is to deter a nuclear attack against this country or its allies.
With this limited purpose of deterrence, a new nuclear posture review can commit the United States to take as many warheads off hair-trigger alert as possible, to refuse to build or design any new nuclear weapons systems, and to negotiate with Russia for even deeper cuts in nuclear arsenals.
These changes to the nuclear posture review can point the way toward real national and international security.
