Trump is supported by utterly incompetent imbeciles such as J.D. Vance, who the Iranians have played like a fiddle at the peace talks in Switzerland. The Americans arrived early, and went in first to the negotiating room, giving the Iranians the pyschological edge. As seasoned negotiation veterans have said, the losing party is the first to enter the room, the victors enter last.
Then the negotiations have stalled at every turn, with the Iranians knowing full well they're playing with a handful of aces. When asked if the U.S. was demanding a full and total end to Iran's nuclear programme, Vance only said, "Oh yes, we'll be negotiating an end to their nuclear programme" - like it was now of secondary importance.
If the U.S. really were the winners here, they'd demand the end to Iran's nuclear programme as a primary and non-negotiable demand. Vance is a totally incompetent f****** loser, he couldn't negotiate his way out of a paper bag.
