The war will not end up as a real war. It will be a guerrilla action. It will be small scale actions against diverse targets that are not and can not be defended. It will be more against property and liberal infrastructure than people. Some may actually die, but they will mostly be those in the wrong place at the wrong time. ...... collateral damage.
It will boil down to truck drivers. The question will be “do I want to risk my truck and my life driving into that city?” Enough will decide not to venture into the cities targeted that there will be problems with inadequate stuff .
“Problems” doesn’t begin to cover it.
