I haven't seen the quotes from them, so I cannot evaluate them.
Well from what I have read Iranian Foreign Minister Abbas Araghchi says negotiations are off the table. If that is so, then what those two negotiators said or did not say is a moot point.
Frankly, I find it difficult to keep up because comments about what is happening in this war, change hourly and also depend on who is saying it, Trump, Hedgeseth, Steve Witkoff, Jared Kushner, JD Vance, and/or Karoline Leavitt, etc.
