Regarding Taiwan, barring WWIII it’s not all bad. (Did I just write that?)
Taiwan has the most progressive democratic govt in East Asia and the first democratically elected female head of state in the history of any Chinese society.
Beijing is run by a nasty arrogant thug promoting his own personality cult and bent on expansionism. I understand the context. I study the region. Trump’s nuts. We know that.
Every reasonable Chinese person (I.e. people who respect human rights) respects the democratic achievements of Taiwan, despite its many faults, and are highly critical of Xi, who has zero respect for rights and is (also) a certified megalomaniac.
I have friends who are survivors of Tiananmen and US citizens today and virulently anti Trump who will not be sad about this. Taiwanese will not submit to Beijing until Beijing respects rights. Is Trump still nuts? Of course. Has Xi shown anyone respect? No. Is this dangerous? Not sure, but probably and hopefully not.
