The geopolitical limits of Donald Trump's power and ability: He occasionally claims to be mad about what a foreign leader does. Putin, Netenyahoo. And Xi, when he gives him an opportunity, no doubt.
Thus far, 8 months in, it goes absolutely no farther than that.
Powerful "leadership," no doubt.
(how much do you suppose Chinese planning for Taiwan has ramped up since Xi had it confirmed [as if he had to guess] that the worse Trump will do is pretend to be mad?)
