History says so. The one thing that a country would protect is its own territory. The world sees how much destruction had been done to countries that are developing like Libya, Syria, Iraq, and Afghanistan. These countries are destructed when the US arrived, they don't want that to happen to them.
It's sure not surprising that they will try to acquire islands to have military weapons there. Taiwan will be used with more military bases there if they unite Taiwan and China. Is it fair to unify Taiwan and China, well it's their affair and I don't think someone has to go between them.
Alaska was once owned by Russia, I guess they can work that out to do transactions again and I guess Biden can make negotiations. Do you think this is what they talked about with Putin?
Taiwan doesn't want someone to go between what China wants? They broke from China in 1949 when Mao took over and Chiang Kai-shek fled with the remaining followers of capitalism of old to Taiwan. Do not compare them with Hong Kong which had a charter with Britain and you can argue that charter ended in 99 years so the land would be given to whoever is governing the Chinese mainland. Taiwan in contrast wants nothing to do with China and more to do with the western countries and their ideals. Desiring China to own Taiwan is like wanting Japan to have dominion over Hawaii during WWII.
