There are parts of the right that are almost as dedicated to Taiwan as to Israel. To some extent, this is based on sound strategic reasons; if you doubt it, find Taiwan on a map relative to Japan and South Korea. But there is an element of passionate ideological loathing of Chinese communism as well, along with a sprinkling of racism.
If Trump makes anything like the grand bargain I have described in a previous post, it will be viewed as a betrayal by this part of the right. Will that result in a rebellion with meaningful results? If the event occurs towards the end of Trump’s term, and Trump is clearly viewed as a failure by the electorate, maybe. Otherwise, history tells us that GOP politicians are way too fearful of the MAGA base, which is indifferent to Taiwan, to do anything seen as hostile to Trump.
