“Then it would be an occupation, not an invasion, they would merely absorb their conquered land and wealth. “
One of the things about NeoCons, is they cannot conceive of any follow-on to military victory other than an overseas invasion and occupation.
The idea of reducing the military back to peacetime levels, and going back to peace-time activities never occurs to them.
In your mind then, when America and the nations of Europe are defeated and broken up and no longer exist because of the world-wide military successes of China/Russia, then the world will find peace and Red China/Russia will mostly eliminate their militaries, and basically the world will be a better place without Western man and the Americans.
