Bolton, who has always been friendly to Taiwan, also says that after President Trump found out that Wall Street financiers made a fortune in China, Trump stated that he is particularly dyspeptic about Taiwan. Furthermore, it appears that on several occasions, Trump pointed at the tip of his pen and said “This is Taiwan,” and then pointed at the Oval Office desk and said “This is China.” Bolton writes, “That pretty much sums up the promises and obligations that the United States has for its democratic allies.”
A lot of the stuff are behind a paywall now.
