Not anything about doctrine or tactics but I haven't seen these questions asked.
1. Can the Federal govt party politics unite an American populace who are fed up with the lies of why we fought in Afghanistan and Iraq and now Syria?
2. Can we stomach high losses of American blood, I.E. a couple aircraft carriers, cruisers, frigates and destroyers with all hands. Destruction of Kadena, Andersen , and Elmendorf?
3. Will China if they find things going south use nuclear weapons, will we? China only cares if the CCP survives.
4. Will we able to stomach total war, using extreme violence to drown millions of Chinese troops in the sea.
5. Can we coral Corporate CEO's who will sell their daughters into sexual slaves just to have a good qtr and do business with China? Plus can retailers and manufacturers handle not getting their cheap shit from China? Would world trade disappear. and could China feed itself without American, Canadian exports? Could Americans put up with rationing?
6. And the 800# gorilla in the room, are the present POTUS and VPOTUS up for the job of being War leaders?
