False, this is a fundamental misunderstanding of the constitution.
There are of course procedures in place to launch but they exist at the pleasure of the president. There is currently no statute that prohibits first use of nuclear weapons by the president and even if there were there’s a decent chance it would be unconstitutional.
The procedures that do exist are ones developed by DOD and therefore inherently cannot bind the president as he is the source of authority behind all of them.
I didn't say anything about the constitution. where did you get that or are you assuming that is what I meant? I am very familiar with the DoD and DoE rules when it comes to nukes. and I worked on First Strike Tomahawk missiles. I really don't think you know what you are talking about other than the shit you find on google. as I said earlier. the president can not just wake up one day and decide to toss nukes at somebody. that will never happen. if Milley thinks he stopped such a thing he is seriously mentally impaired.
