Trump looks like he's angling to use Taiwan as a pawn in negotiations with the Chinese.
This sounds too much like Obama or Clinton in general....and let's not forget that it was Carter who sold out Taiwan to China in 1979. Presidents after that just went along because there's an unwritten rule, your not supposed to disrespect a president's legacy whether or not you agree, so US had to always follow Carter's stupidity in recognizing Beijing as "One China."
Trump is different. Being a businessman, he sees through all the enigma surrounding this political fiction and perhaps will start moving in a direction to blow it to smithereens if the opportunity affords itself. Trump said he sees no reason why another country should prevent him talking to a leader in another country. That is tantamount to tacitly admitting Taiwan is a country. It may be uncouth to establishment polititicians, but practically speaking, that is reality. I hope he succeeds.
In 1979, the Democrat Congress were so incensed at Democrat Carter for selling out Taiwan by recognizing Beijing, that they drew up the Taiwan Relations Act to protect Taiwan and it's democracy from China coming in and taking their "possession" since Carter seemed so ostensibly to agree. It necessarily involves the USA in military conflict should China invade the island -- it's our law. I was always afraid that Obama, being chief executive would ignore it if it got down to brass tacks. This is why US always gets upset when Taiwan strays too much from one-China.
True, Trump himself has said himself he would use the issue for economic bargaining, but how would he sell out Taiwan exactly? The worst he could do is just cool it, back down and not use the issue if China proves compliant, which makes him equal to what other presidents have (or rather haven't) done. Have they sold out Taiwan? But if China proves difficult, I think he would rather enjoy using the issue to reconcile the fiction with reality.....with what makes sense in a real world.
