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?
