Shortly after the election I had a dream where Trump was trying to nuke California. Congress was trying to impeach him, the secretary of defense was telling the military to disobey the president's orders, Trump was trying to get the military to arrest the secretary of defense and the senate and house leaders, and the whole world was basically watching and hold it's breath. I still remember it like it really happened, and don't look forward to a replay.
I read somewhere recently (probably on here) that in the late days of the Nixon administration when he was drinking very heavily certain key people were told to (illegally) not fire nukes on the order of the president unless Kissinger gave them the go ahead. So there is some hope.
ETA: Though in real life the tracker on CNN would just say: President's choice to nuke California raises concerns with some Republicans in Congress.
