Israel has more than just US interests on their mind.
I know, but my point is that Israel and Iran can never get along in their current state. Either Israel would have to stop being a US protectorate or Iran would have to submit to US interests. Neither is going to happen, so fruitful diplomacy isn’t possible. That (and the whole settler colonialism thing) is the core reason why they’ve been in conflict for decades. The US can’t buy Iran’s cooperation because Iran accepting that would itself be an act of submission. Israel has its own issues with Iran, but that’s irrelevant compared to (and caused by) the fundamental geopolitical incompatibility between the two states.
Um… No US weapons, and reparations for the destruction in Gaza, the West Bank and Lebanon, for one. Then being forced to return settlements and take part in an equal and just peace. Pretty much fixing the mess they made.
