His segment starts around the 1:03 mark. I listened up to the 1:20 mark, but I need to head out and get some things done, so I have not gotten to the specific part where he calls the negotiations fake.

Spoiler alert: he doesn't.

I pulled up the transcript. He doesn't talk about the negotiations at all. Almost all of his discussion on Iran is spent on talking about the ways he believes Israel and Netanyahu dragged us into the war, and lamenting the perfidious influence Israel has on U.S. policy. There's no discussion that the negotiations are fake by Joe Kent. Or even by the TYT staff - just an offhand comment asserting that since the negotiations aren't direct talks (the Iranians aren't in the room, back then) they're nothing more than Trump shadowboxing with himself.

Curious why the title mentions "Fake Negotiations" when there's nothing in the more than two hours of the episode about the negotiations being fake. Probably that just got the best A/B results in generating clicks.
