I suspect that the IRGC will be the last ones with empty canteens.
They will still be empty eventually. It might still become a stable situation though. If you look at pictures from North Korea the only person who doesn't look malnourished is Kim Jong Un. Otoh water is different from food. Also it's the middle east. They might have to cut back on their aggression but their antagonists (who by now is literally everyone) won't.
It's all British/American fault. /s
Dont forget the mighty CIA.. so mighty they couldn't even stop trump from ruining it for the military industrial conplex with isolationism. Anything to prevent the realization that left policies are and where rejected by the people.. if you start introspection, the movement immolates.
It is a crying shame and the Iranians deserve better. At the moment 16 million people may find themselves without water in the near future. I'm lost for words.
If one positive thing could be found in this situation it might finally be the thing that brings down the regime. I think it's fair to say this year has been an annus horribilis for them.
