That’s why Vietnam and India are moving to improve relations with the US. South Korean policy will be split as long as NK is separate and US forces are still in SK. I don’t believe the current negotiation will result in NK removing all nukes and leading to a re-unification.
The US Taiwan policy has always been ambiguous – I think the thinking always has been status quo and defer the problem until later.
Yes, the Japanese never really apologized to Asia for WWII – not sure what you mean about Germany and US since the US had the Marshall plan and defended W Germany and W. Berlin. We still have many military forces and facilities in Germany today. Hard to imagine any way Japan would have in the past and will align with China – there’s too much historical animosity between the cultures for now. If anything, Japan knows its future is tied to the US and will align even more to the US position – it gives them better options as a counterbalance to China.
What’s unknown is how demographics will play into the geo-politics. Japan is the worst in this area, China has a huge problem in 20 years, the US looks the best of the 3. Geo-politically though, the world looks headed to more conflict between larger powers then less – but the past few decades have been relatively the most peaceful in human history.
Thanks for an interesting, non-politicized, reasoned discussion, BTW
