President Donald Trump Nuke Watch
"With a single phone call, the commander in chief has virtually unlimited power to rain down nuclear weapons on any adversarial regime and country at any time. You might imagine this awesome executive power would be hamstrung with checks and balances, but by law, custom and congressional deference there may be no responsibility where the president has more absolute control. There is no advice and consent by the Senate."
