Democrats in the U.S. House and Senate introduced legislation last week to prevent the U.S. from using nuclear weapons unless first attacked by nuclear weapons from another country. Ideally, the bill will induce a long-needed reconsideration of U.S. nuclear weapons policy — and lead to the conclusion that “The No First Use Act” would hobble U.S. national interests and make the world a more dangerous place.

First, let us assume that the bill, one of whose sponsors is senator and presidential candidate Elizabeth Warren, actually would have binding force in some of the emergency cases where this might be an issue to begin with. Otherwise, it is an empty declaration.
