In order to stabilize the Pakistani portion of Greater Iran, you would probably find it necessary to kill no less than at least 50 thousand people and instate laws whereby public killing of insurrectionists and the unlawful is made. In order to annex all of Kashmir into it, you would probably have to cross no less than a million deaths, with a displacement of thousands if not tens of thousands of people. Ironically, you wouldn't encounter overmuch friction in Afghanistan when its matter is brought about. Tajikistan will willingly join only after everything is peaceful, clean and nice.
The overall contention against India would see at least 5 million people dead. Perhaps 5 or 20 million more to that given national enmity and stuff.
Everyone will be rushing forward to a veritable slaughterhouse endlessly until it's determined doing it any longer is meaningless.
Though even then, you'll have nationalists trying again and again, only to end up slaughtered again and again and again and again and again.
It's quite brutal.
For about 5 years, Kashmir, though eventually all part of Greater Iran, will be a no mans land, and anyone who sets foot into it will simply be killed by a drone.
If the Indian government ever wants to solve some of its societal issues akin to how Russia's doing the same via Ukraine, they'll send off several men to fight in Kashmir under the propaganda and blatant lie of it being for the greater good, when in reality it's a mission merely to flush the many and keep things cool, and so all these men will essentially be exploded in 47 different ways by 47 different drones. That's to say, they'll be put through a slaughterhouse.
Once the smoke clears and the analysis done, the total number of deaths in the Greater Iran-India-China war will amount to a toll vastly superior than the number of deaths from WW1, WW2 and the 30 year war combined. It's precisely in this war wherein Russia will re-enter Central Asia and begin reannexing portions of it left and right while at the same time absorbing entire countries and demarcating them with the label 'extraneous lands'.
The theatre in the eastern portion of Turkey will be like this but on a scale of a different dimension that ensues in the Mediterranean and Black sea turning red with blood. Not good at all. But well, China ends up with South Tibet, Bhutan, Sikkim and a new puppet nation from the 7 sisters. Bangladesh ends up with West Bengal. Russia inches closer to the US
