Senators seek attrition in old nuclear warheads

Three Senate arms control experts proposed a plan they said would require the United States and the Soviet Union to destroy as many as three nuclear warheads for every new one they deploy.

The two-step plan, advanced by Democrat Sam Nunn of Georgia and Republicans William Cohen of Maine and Charles Percy of Illinois, envisions a steadily declining limit on the total destructive capacity of the US and Soviet nuclear arsenals as well as reductions in ballistic missile warheads.
