it's absurd, but let's consider the premise - that donald trump will make good deals.
let me ask you this question: would you expect donald trump to keep his end of the bargain? so, why would you expect the chinese or the russians to?
suppose he makes a deal with the russians that lets the russians stay in syria. would putin expect trump to live up to his side of the deal? and, if not, why would he carry out his side of the deal?
i could accept the premise, however tentatively, if the deal maker were perceived as honest. reagan was a lunatic, but he was an honest dunce, too. trump cannot project that kind of trust and won't get it.
talk about "playing a hand", huh? the entire world knows his word is worthless.
if he makes any deals at all, they'll be terrible. there's no other possible outcome.
