There is a spectrum of options between “do nothing” and “go to war”. I would not support a US military intervention in a war between Taiwan and the CCP.

Clearly, the CCP is nowhere near on the scale of Nazi Germany, though when we talk of appeasement, it wasn’t quite at the levels of conquering all of Eastern Europe at the time, but I’m not going to split hairs over that - your point that I shouldn’t compare them is completely valid and fair.

I think continuing to keep things at a stalemate where neither country gets invaded is the best state of affairs for the time being, until something changes geopolitically. For that reason, I am not going to decry the supply of weapons to Taiwan, because that provides disincentive for an invasion of Taiwan, and makes military conflict less likely.
