One wishes. The Israelis can and likely will defy the US, expecting, correctly, that their influence in DC will contain any fallout. This is why I still think we’re gonna see a separate peace, even if a de facto one. Ie, a fudge.
The entire discussion about whether Israel will or will not accept any agreement between the US and Iran is a waste of time, nothing but an exercise in smoke and mirrors.
Israel will do as it is told because it has no choice but to do precisely as it is told.
If Israel rejects or acts to undermine the agreement, and does so without consequence, that is because it has been authorized and perhaps encouraged to do so by Washington.
It really is that simple.
