Thanks to Eve Mary Verde for her reminder that the legacy of nuclear testing remains with us some 67 years later ("Trinity: The plight of 'downwinders,'" Readers' Forum, July 20).

Fortunately, this year also marks another anniversary — a more hopeful one. Twenty years ago on Sept. 13, 1992, after a sustained national grass-roots lobbying campaign led by disarmament groups, the U.S. Senate adopted a nine-month U.S. testing moratorium.

The moratorium placed strict conditions on any further U.S. testing, and required the U.S. to enter test ban negotiations. On Oct. 2, 1992, President George H.W. Bush signed the moratorium. Since our military and national security experts tell us that we have no plans nor need to restart testing in the future, it is time to make the moratorium permanent.

In 1996, President Bill Clinton signed the Comprehensive Nuclear Test Ban Treaty, or CTBT, but in 1999 the Senate failed to ratify it. It's time for the U.S. Senate to ratify the CTBT and move us one step closer to a nuclear weapons free world.
