Whether we survive is still open to debate following today's Senate hearing on authority to use nuclear weapons.
Can they stop Trump in reality, under pressure, with just seconds to make the decision?
Not clear. They don't know. They'll decide when it happens. Maybe toss a coin.
"Retired Gen Robert Kehler ... told the Senate committee that he would have refused to have carried out a nuclear first strike on presidential orders, if he believed it did not meet the requirements of proportionality and necessity under the law of armed conflict.
“I would have said: I’m not ready to proceed,” Kehler said.
“Then what happens?” he was asked.
“I don’t know,” he replied. “Fortunately, these are all hypothetical scenarios. There is the human factor in our system. There is a human element to this.
“It would be a very interesting constitutional situation, I believe. The military is obligated to follow legal orders but is not obligated to follow illegal orders ... If there is an illegal order presented to the military, the military is obligated to refuse to follow it. The question is the process leading to that determination and how you arrive at that. I would concede to you that would be a very difficult process and a very difficult conversation.”
...
Ed Markey, a Democratic senator from Massachusetts who is sponsoring legislation that would
limit the president’s authority to launch a first nuclear strike, said he was not reassured by Kehler’s arguments
“I don’t have confidence that a military chain of command would reject an order by the president to launch nuclear weapons in a preventative nuclear war situation ... I think that would be abdicating the responsibility of the US Congress to a group of generals who in many instances would have been appointed by the commander-in-chief,
Donald Trump. That’s a very thin reed on which to have the fate of the planet being dependent.”"
