@Oldschool a counter argument , that's where the Chinese asymmetric warfare came in?( flexibility) A zero sum strategy is effective if you had the advantage across the board. At present we're heading Into a multi polar world and that strategy is ineffective cause its inflexible. Each countries had its owned interest and they will join if their interest coincide. Your example of Ukraine is a good one but their main interest and goal is to be part of EU, all other consideration is put aside. And remember China survive even after being hemmed in both by the Soviet Union and the US during the cold war. What I'm afraid of is that the opposite will happen and the US will be in for a surprises cause alienating both China, Russia and also Iran at the same time is a worst strategic move one leader can make.Because US mindset is zero sum. If your opponent is zero sum what do you do even if you thought is wrong!
Prepare for worst! You have no choice!
