Parsi's analysis seems spot-on except Putin certainly didn't want a westward-facing treaty with Iran, and I'm sure he pressured Trump to crash out more than Bibi did. But then Trump was elected with both's help, so that's how we got our Mideast policy run by Jared, Erik Prince, and other dick less slime all actors. Biden has to recover gracefully from that abandonment of US interests while still holding up the goals oof the negotiations - even as Iran's new Pres is more hardline and Israel's is prolly more conservative than Bibi bot not the showboatter/bullshitter Bibi is. So good luck to Biden, but think he has the skill for something positive. Yes, side channel talks out of the public eye. When Hillary mentioned this as a standard necessary diplomatic practice, everyone acted as if she'd kissed the devil - such lack of transparency! But transparency is where all Bibi's showboatting was happening, screwing actual compromise..

see this whole Twitter thread as well as article, very good on "inside Israel politics" on topic:
