Are NATO-based nuclear weapons really an advantage in a dangerous world, as Brent Scowcroft, Stephen J. Hadley and Franklin Miller suggested in their Aug. 18 op-ed, “A dangerous proposition”? They are not. They make the world a far more dangerous place.

Nuclear deterrence is not a guarantee of security. Rather, it is a hypothesis about human behavior, a hypothesis that has come close to failing on many occasions. Additionally, nuclear weapons are not “political weapons,” as the writers asserted. They are weapons of mass extermination.

The United States and the other nuclear-armed countries are obligated under the terms of the Nuclear Non-Proliferation Treaty and/or customary international law to pursue negotiations in good faith for an end to the nuclear arms race and complete nuclear disarmament. This is the substance of the Nuclear Zero lawsuits brought by the Marshall Islands against the nine nuclear-armed countries at the International Court of Justice and in U.S. federal court. The United States continues to evade its obligations.

Rather than continuing to posture with its nuclear weapons in Europe, the United States should be leading the way in convening negotiations to eliminate all nuclear weapons for its own security and that of all the world’s inhabitants.
