Warren introduces bill to ban U.S. first-strike nuclear option

The Massachusetts Democrat has introduced a bill with Democratic U.S. Rep. Adam Smith of Washington that would make it the official policy of the United States not to use nuclear weapons first.

The lawmakers say the United States currently retains the option to be the first to use nuclear weapons in a conflict, even in response to a non-nuclear attack.

They said banning the use of nuclear weapons for first-strike purposes would “reduce the chances of a nuclear miscalculation.”
