I think you're confused. The one-china policy or the alternative was NEVER a campaign promise. It came about after he had won the election in December 2016, when the leader of Taiwan phoned to congratulate him and they talked about the situation at that time. When you acknowledge that it is not logical to lump this in with his pre-election promises, we can talk about the other points you raised. Until then your post must be classified as disinformation. The time-frames are simply, wrong.
