I am not sure what rank you were in the US Army, I was on the way to becoming a Sergeant Major in the Canadian forces when the Cuba Crisis broke out and I resigned.
We were taught that you need to annihilate your enemy and occupy territory in order to win. The last time the USA won a war was when they occupied Germany and Japan after annihilating them at great cost to innocent human lives, They still have soldiers based there after a full occupation.
I do not foresee Gaza ever being rebuilt because it cannot be deNazified in this generation. The population is brainwashed into Islam (a death cult) and brainwashed into martyrdom and the destruction of the other.
You are seeing it in Europe and now even in the USA. The nightmare is just starting.
