Your scenario of the total destruction of an American city is precisely what North Korea is threatening us with. Kim Jong-un isn’t going to use a rifle with a silencer, Hillary’s most feared weapon.  It will be an array of nuclear warhead tipped missles. 
It makes a big difference to the Trump Administration and I think it is time for you to become less partisan and more supportive of our President.  Otherwise your scenario may come true because it would make no difference to YOU whatsoever.
