arms control

When President-elect Joe Biden is sworn into office, he'll have 16 days to work with Russian President Vladimir Putin to save the last arms control treaty limiting U.S. and Russian nuclear arsenals.

The U.S. and Russia still inspect each other's nuclear arsenals and have sharply curtailed the number of weapons poised to launch. That's thanks to two arms control treaties, which are now at risk.

A U.S. general says Russia has violated a longstanding arms control treaty by deploying new missiles. It was the first official, public assertion that these missiles are fully operational.
