United States currently has about 20 nuclear subs, missile firing, each submarine carries 20 MIRVED cruise missiles, with 10 Warheads each.
We are talking 4000 or so nukes, each about 20 times more powerful than the bombs dropped on Japan.
These nukes or subs are not immobilized by emp. Any war will be short if the CIC has the stones to correctly respond to our being attacked
“Any war will be short if the CIC has the stones”
That word “if” is huge.
