Yeah. I'm on the one hand skeptical of the IRGC. On the other hand, I could easily see them making a play for power. There's a lot that could happen. Basically, I expect some manner of chaos when that happens, and it's worth the US's time to wait it out and basically force Iran to effectively save-or-die, rather than fighting in the near future.The whole point of existence of IRGC with all its money and separate armed forces is to prevent such normalization. But we're talking civil war here, one resulting in total loss by IRGC and aligned forces. Its foreign adventures are only a side gig for them, their main job is to be, as the name implies the revolutionary guard, as in guarding the revolution.
Also, the IRGC is about keeping Iran Islamic. I don't know how many of them deeply care that they are anti-US, that's more incidental but not necessary.
I'm thinking of a non-secular Iran. Obviously, a secular Iran is an easy win. But a Theocratic empire that doesn't hate the US is also possible.Israel actually had great relations with Iran before the revolution. As soon as Iran stops being interested in islamic empire building by asserting to the Sunnis that they are better at it than the Sunni powers (plz convert), the old framework where secular Iran has plenty of need for allies against the backwards barbarian Sunni hordes encircling them would reassert itself.
