this is not the soviets who subscribed to Mutually Assured Destruction after losing tens of millions of citizens in the 1900s. These are religious fanatics who must be destroyed. Meaning the people in power.
Shias are forbiden from waging Jihad the way the Sunis do until the MAadi arrives triggered by a final world conflict.,
I believe the Mullahs want to trigger that to put the Imams into agreement to start the Jihad.
