On the Fact that at One Point Donald Trump Said that as President He Might Attempt to Renegotiate Our Debt - so (for example), Instead of Giving that Little Old Lady in Portland Maine or Beijing China the $500 that We Owe Them for that Bond We Give Them $300

Yeah, that's called defaulting and it would probably a) destroy the dollar, b) prevent folks from purchasing our debt in the future, and c) tank the economy, the stock market, etc........Of course it would also create a beautiful bookend to his equally disastrous trade proposals and so there's that.
