What would such predelegated instructions look like, how large is the state space in that flowchart? How effective is control theory with a tiny state space? This doesn't sound like a survival plan, but a self-splintering plan: some military units will capitulate or defect while others fight on, when pushed till the edge, or is there some kind of direct-democracy-within-the-IRGC? that doesn't sound plausible...
Basically sounds like the military from Imperial Japan during the end of WW2, with scattered units continuing to fight, surrender not believed an option, not aware, or in disbelief that Japan has surrendered...
Let's hope it doesn't have to lead to the same conclusion?
The Swedish military famously works the same way (or at least used to) - they're trained to uphold the Swedish constitution themselves regardless of what their leadership says, with the result that they saved many lives in former Yugoslavia despite orders not to intervene: https://www.realcleardefense.com/articles/2017/09/20/trigger... .
This isn't a complicated war. The US can't and won't do occupations, so the only thing you need to do is cause problems till they leave.
Iran doesn't have to conventionally defeat the US military and can't: so they're just not doing that, and instead going after valuable economic targets which are politically sensitive to Americans and impossible to defend since they're risk sensitive.
