Sleep well...Trump can launch nuclear weapons whenever he wants, with or without Mattis
The abrupt and pointed resignation of Secretary of Defense Jim Mattis on Thursday alarmed official Washington. Sen. Mark R. Warner (D-Va.) called him an “an island of stability amid the chaos of the Trump administration.” Retiring Sen. Jeff Flake (R-Ariz.) told The Washington Post that “having Mattis there gave all of us a great deal more comfort than we have now.”
Mattis’s departure seems to be provoking unease, especially considering how dangerous our nuclear-command arrangements are. The notion that Mattis, a former four-star Marine Corps general, could have blocked or defied a move by Trump to impulsively launch nuclear weapons may have seemed comforting, but it shouldn’t have been. The secretary of defense has no legal position in the nuclear chain of command, and any attempts by a secretary of defense to prevent the president from exercising the authority to use nuclear weapons would be undemocratic and illegal. With or without Mattis, the president has unchecked and complete authority to launch nuclear weapons based on his sole discretion.
The reaction to Mattis’s resignation, however, could open the door for the new Congress to create long-overdue legal barriers preventing the president from initiating a nuclear strike. Such a step could be implemented without any negative impact on U.S. security or that of our allies.
Every day, the U.S. nuclear early warning system is triggered by some event or another, mostly civilian and military rocket launches by one or more of a dozen countries with ballistic missiles. When such launches appear to threaten North America, the head of U.S. Strategic Command is alerted, and sometimes these alerts warrant the urgent notification of the president. That alert comes by way of a direct call from the Strategic Command or via the White House Situation Room, the emergency-operations bunker beneath the East Wing, or the national security adviser. Partly a remnant of the Cold War, this system remains in place today to ensure the president can be notified quickly of any direct threat to the United States’ nuclear arsenal and the facilities that control it. That way, he can launch nuclear missiles before they are destroyed or the U.S. government is incapacitated by incoming weapons.
