There is a system of checks and balances that are made to prevent the U.S. president to illegally order a nuclear strike, but a commander in chief is not able to be stopped if they try to order a strike. "If President Trump were to decide that it's time to put (North Korean leader) Kim Jong Un in his place once and for all, he would choose a plan that already exists. And it would be almost impossible in my view to override a decision to implement that option," Bruce G. Blair, a former nuclear weapon launch officer and co-creator of the Global Zero group. The exact procedure that would be followed has been criticized by congress Trump's experience and authority to wage war at a time of elevated strains with North Korea over its nuclear desires.
