Unless there was never an intention of achieving an agreement, just looking like you are achieving an agreement. Even after the work of Doge, the State Department is crammed full of extremely experienced negotiators. Its possible there are some (the Heritage Foundation), interested in a bigger picture, who want the President to fail, and want to personalise that as much as possible, so there is no hint of any Trump family influence remaining. This is Technocracy at work; Trump provides the opportunity to create real change that actually realigns US politics. He has no personal politics, he never even read their 900 page manifesto. Vance is a technocrat. The technocrat doesn't believe charisma is needed to gain support, just doing a good job. While Thatcher was a Conviction Politician, her government was really more like a technocracy, pushing through the tough and unpopular policies that needed to be done. The American system of candidate nominations is nothing more than a beauty contest, with figures saying anything to be liked, and not saying the things people don't like, but need to hear (in their view). Technocracy, while it claims to be anti-politics, is still as much a political movement as socialism, and probably just as wrong. But the exponents still believe in things.
