If you’ll recall, Trump made waves after the election when he openly embraced Taiwan and said he might recognize them. Apparently, this caused a row and China refused to talk to Trump primarily because of these two tweets.
Well, the New York Times wrote an article yesterday about this and the call they had yesterday where Trump finally recognized the One China Policy, and it made light of the fact that it had been four months since anyone spoke.
Somehow, Trump heard about the article but did not bother to read it. He went on the attack immediately, showing that he is delusional or in the beginning stages of Dementia.
