Trump seems to like the pomp of a 'win'... real or imagined.

I think it will come down to how quickly things escalate and if Trump runs or wins in 2020. It's possible the Chinese will hold out until then and adjust accordingly... I think the stakes are high on both sides. Thus far China has had virtually no economic push back to the transfer of jobs and wealth from the US. If the Chinese can break through, I doubt anything will stop China's accent. Likewise, if Trump doesn't persist it's possible he'll lose his voter base and it's unlikely that any other administration will have the stomach to take on China.

I think it's possible that if a few other things go Trump's way (North Korean, Iran, the wall) he'll have enough voter support for a second term. I don't see a blue wave forming if that happens, nor do I see a large pool of credible Democratic Party presidential candidates emerging no matter how uncouth Trump's rhetoric. A perfect example is Ocasio-Cortez and her socialist policies who I don't see appealing to a large enough voter base.
