September 2023 is the sixtieth anniversary of U.S. and Soviet ratification of the world's first significant nuclear arms control agreement, the Partial Test Ban Treaty.  The history of this treaty and its successors shows us that arms control and disarmament treaties have helped to curb the nuclear arms race and prevent nuclear war.  Similarly, the revived march toward nuclear catastrophe can be halted by finally banning nuclear weapons -- if people will demand it.
