No worries. I'm not generally OK with abandoning allies, but Taiwan has had decades to figure out a relationship with China. Obviously that's a very overly simplistic statement but is the US really prepared to go to war with China (or they with us) over Taiwan?
In contrast, I was utterly disgusted with the abandonment of the Kurds after they had literally gone to war in support of and with the US in Syria. The Kurds have bled with the US military in support of US geo political goals, and they were cast aside without a second thought. It was despicable to me.
I likewise respect the difference in opinion and civil conversation.
Maybe you should be asking why China is willing to go to war with us over Taiwan? This is an agreement they signed onto. Are we also allowed to go take Panama over again then... or how does this play out long term I wonder if we become unable to offer up any response at all?
Also by now everyone is aware of those re-education camps. Imagine what it must feel like to live somewhere they are about to take over. If Japan, South Korea, Philippines all decide the economic center of gravity has shifted it will only be a matter of months until they start offering China the store to avoid being re-educated. As someone born in a free country I can't even imagine what I would give up to avoid that fate.
Finally as a democrat... allowing the Asian voters to go the way of the 'Cuban' voter is a bad move politically. White guilt isn't a universal American trait.
