So if Mattis says "no, you lunatic" then Trump fires him - what happens then? Does Trump turn to the next guy in the room and say "You are SoD - fire my nukes"? And so on until someone does?
What's worrying me is there have already been so many incidences where, 12 months ago, we'd all be saying "That could never happen" "Checks and balances" "If xx happened then yy would step in"
But they haven't. Nothing has been done to stop him, no one has stepped in. Which leads me to conclude no one will, even when he's got his finger on the button.
I am very pessimistic and worried today :(
