Who knows where the first shot will be fired? That'll probably be disputed. People are shooting at each other already, every day. It won't be like the first CW with uniforms and troops and front lines. It'll be chaotic with flashpoints in unlikely places. Lawlessness and bloody violence. Lots of collateral damage. Innocent and not-so-innocent lives taken.
The US army? The police? I don't know whose side they will be on, that'll probably vary from place to place.
And worst of all, I don't know who will win, or how you even know that it's over.
It’s over when you’re dead.
