Well, now that it has happened we can all know, based on actual concrete proof, that not a single person in the US military hierarchy obeys the law that requires the refusal of unlawful/unconstitutional orders.

We have transitioned from a military under Constitutional and statutory limitations to a military that is a Republican Guard, or in older terms, a Praetorian Guard.

If we ever do, if ever, return to a nation of laws then every person in the entire military hierarchy is going to have to be charged and disciplined - because no one, not a one, even questioned, much less refused, the unlawful/unconstitutional orders to go to war with Iran.
