"Would you have US generals refuse orders from the president?" - Danite You apparently negate the right, nay, the duty of generals, to refuse orders from the president, when they perceive them to be unjustful. Every soldier, from the five-star-general down to the private, has his own duty in assessing the justfulness of the orders given to him. That's the prime reason why Jodl and Keitel received the death penalty at Nuremberg - they obeyed their Fuehrer's order in signing the so-called Kommissarbefehl, which meant the murder of every (perceived) communist civilian in Russia. Starting a war, e.g., against Iran, for a perceived but not imminent threat, without prior authorization from the UNSC constitutes waging a war of aggression, which equally is a war crime at least since Nuremberg. Not only the president who starts such, but also the generals may be held accountable for such.
