Now More Than Ever: The Case for the Comprehensive Test Ban Treaty

By Tom Z. Collina with Daryl G. Kimball

Nuclear testing is a dangerous and unnecessary vestige of the Cold War that the United States rejected almost 20 years ago. There is no military justification for resuming U.S. testing, and the United States does not need nuclear testing to maintain the effectiveness and reliability of its nuclear deterrent.

The 1996 Comprehensive Nuclear Test Ban Treaty (CTBT) is an essential part of a commonsense strategy to reduce nuclear dangers.

It is in the U.S. national security interest to prevent nuclear weapons testing by others and to improve the U.S. and international ability to monitor compliance with the treaty.

A growing list of bipartisan leaders agree that by ratifying the CTBT, the United States stands to gain an important constraint on the ability of other states to build new and more deadly nuclear weapons that could pose a greater threat to American security.

This briefing book reviews the key facts and issues at stake.
