The survey of 3,000 Americans was conducted by the Bulletin of the Atomic Scientists and British research firm YouGov, and asked people to consider a scenario in which North Korea had tested a long-range missile and the U.S. government was considering how to respond.

Most did not want their government to launch a preemptive strike, but a large minority supported such a strike, whether by conventional or nuclear weapons.

“For many of these hawks, support for an attack, even in a preventive war, does not significantly decrease when the story says that the United States would use nuclear weapons that are expected to kill 1 million North Korean civilians,” the report found.
