Nuclear experts are warning, using some of their most urgent language since President Trump took office, that Hawaii’s false alarm, in which state agencies alerted locals to a nonexistent missile attack, underscores a growing risk of unintended nuclear war with North Korea.

To understand the connection, which might not be obvious, you need to go back to the tragedy of Korean Air Lines Flight 007.

In 1983, a Korean airliner bound from Anchorage to Seoul, South Korea, strayed into Soviet airspace. Air defense officers, mistaking it for an American spy plane that had been loitering nearby, tried to establish contact. They fired warning shots. When no response came, they shot it down, killing all 269 people on board.
