The top U.S. Nuclear Commander Gen. John Hyten, has said he would reject any order from President Donald Trump for a nuclear strike if it were “illegal.”
Speaking at the Halifax International Security Forum in Nova Scotia, Canada, Hyten, who is the commander of U.S. Strategic Command, shared what would happen if he were ordered to launch a nuclear strike.
“I provide advice to the President,” Hyten said. “He’ll tell me what to do, and if it’s illegal, guess what’s going to happen? I’m going to say, ‘Mr President, that’s illegal.’
“Guess what he’s going to do? He’s going to say, ‘What would be legal?’ And we’ll come up with options of a mix of capabilities to respond to whatever the situation is, and that’s the way it works. It’s not that complicated.”

Hyten’s remarks come after a Senate Foreign Relations Committee hearing this week on the President’s authority to launch nuclear weapons — the first such congressional hearing in more than 40 years.
While the President retains that authority, Hyten publicly emphasised that the U.S. military always has the obligation to follow only legal orders, including those entailing the launch of nuclear weapons.
At the Senate hearing this week, experts testified that the use of nuclear weapons must be proportional to a threat, and the Pentagon has extensive options for use of conventional weapons against North Korea.
Retired Air Force Gen. Robert Kehler, who previously served as the commander of U.S. Strategic Command under President Barack Obama, explained at the hearing that there are layers of safeguards within the current system designed to ensure any order is both legal and proportionally appropriate.
“U.S. nuclear forces operate under strict civilian control. Only the President of the United States can order the employment of U.S. nuclear weapons,” Kehler said.
“This is a system controlled by human beings; nothing happens automatically,” he said, adding that the U.S. military does not blindly follow orders and a presidential order to employ nuclear weapons must be legal.
