To me, it's clear that Israel simply saw the structural forces leading the US long-term decline and the imminent collapse in a few years (they are truly a bit smarter than an average westoid), and then simply decided to squeeze it one last time for their own interest, while they could (using their control).I mean nobody ever accused the chosen people of knowing how to keep together a long lasting empire.
Basically, collapsing Iran into a warring states-like period, they could manipulate, and end up as the hegemon in the region, even in the post-US world. This is why they are also already pointing at Turkey next. However, I think the US will already fall first right during this squeeze, before Iran even collapses.
