Regarding the Dec. 29 editorial “A U.S.-Russia tangle”:

There is another key nuclear treaty that the United States and Russia need to get back on track: The Comprehensive Nuclear Test Ban Treaty has yet to be ratified by the Senate. This treaty would ban all nuclear test explosions. Russia has ratified it, but if we resume nuclear tests, it would likely do the same.

Imagine the international tensions caused by new nuclear testing by the United States and Russia. Imagine China jumping in. Or maybe India and Pakistan would do new test explosions. The costs and dangers of new nuke tests would be huge. Don’t let this treaty break down, too.

The Senate needs to ratify the test ban treaty to end nuclear weapons testing once and for all.
