i'm shia background but not religious myself. nobody in the west knows anything about the shia because it's been reporting on salafist muslims for the last 20 years.  shiism has a martial cultural ethos for fighting to the death at all odds in the event of tyranny. if israel escalates with the shia they will go to war by the millions.  israelis were celebrating total military victory just yesterday but i tried to tell everyone then that its only just starting. if israel and usa go to war with the shia this will go for decades. think perseverance of the taliban but with modern weapons. nuclear weapons and decapitation strikes won't stop them they will just keep going for decades just like the taliban did.  i expect israel will try shock and awe like decapitation strikes and initiating their cia sponsored rebels inside iran but these will only be momentary setbacks as the shia go into holy war mode. israel is vulnerable they have only a few power stations and airbases, if iran hits them with their tens of thousands of missiles it's game over.  tldr war with shia will go for decades. think taliban but with never ending missiles.
