I don’t like the mullah’s in Iran anymore than the next person but no reasonable and sane person would take that to mean “negotiating in good faith.”
Taken as a whole, Trump has not been negotiating with Iran in good faith. That does not mean that Iran has been negotiating in good faith.
If someone takes the first underhanded step, it’s not on the victim to make amends. Iran got burned on JCPOA. Whether we like them or not, you have to address that first before moving on to meaningful talks.
Sure. I think it was probably politically impossible for Iran to negotiate in good faith. That doesn't change that they were not negotiating in good faith.
