This is just my opinion but the main problem most the world's military's have is they are fighting the "Last" war,
and not the next one.
I'm a fan of Sun Tzu, and of 4GW theory.
Presently we are at war, most people in the USA don't know it, and the Americans are losing.
Losing to Democrats and like thinking people in China, Europe, and various other peoples with a
hate for freedom and personal rights.
No shots may ever be fired, but countries will lose resources( they are doing so now), industry will be
controlled by a fewer and few people, food, water, and services will be rationed. The beauty of it all
is much of the population will voluntarily cooperate.
Just look at the USA today.
There will be local conflicts to be sure, but WWIII, no.
