What we’re hearing: “He’s [threatened to withdraw] 100 times. It would totally [screw] us as a country,” said a source who’s discussed the subject with Trump. The source added that Trump has frequently told advisers, “We always get fucked by them [the WTO]. I don’t know why we’re in it. The WTO is designed by the rest of the world to screw the United States.”…

A U.S. withdrawal from the WTO would send global markets into a spiral and cast trillions of dollars of trade into doubt.

It would also blow up an institution that for 70-plus years has been a pillar of global economic and political stability.

The consequences of a U.S. withdrawal are so profound that, like Trump’s senior advisers, the trade community hasn’t seriously entertained the possibility that Trump would try to withdraw.
