To the Editor:

“Will Arms Control Foes Target Another Treaty?,” by Carol Giacomo (Editorial Observer, June 5), chronicles the move to wreck numerous nuclear weapons treaties by John Bolton, the national security adviser, and the Trump administration.

The United States is poised to spend billions of dollars for the upgrade of its nuclear arsenal. The detonation of a few nuclear weapons could destroy most life on earth.

Congress must intervene. The existing nuclear treaties — the Intermediate-Range Nuclear Forces Treaty, the New Start Treaty, the Nonproliferation Treaty and the Comprehensive Test Ban Treaty — must be supported by Congress. Legislation outlawing the first use of nuclear weapons and funding for programs that violate existing treaties should be debated and passed.

Mr. Bolton is dangerous. Strengthening our nuclear arms treaties will be an essential antidote for his apocalyptic policies.
