Prof. Vipin Narang speaks with Washington Post reporter Elizabeth Saunders about the process by which the U.S. president can order a nuclear strike. “The president, and the president alone, possesses the sole authority to order a nuclear launch, and no one can legally stop him or her,” Narang explains. “Despite reports that Pelosi received assurances that there are safeguards in place in the event the president of the United States (POTUS) wants to launch a nuclear weapon, any such meaningful or effective safeguards would be illegal.”
