The Republic of Azerbaijan will take Zanjan, Gilan, West and East Azerbaijan, Qom, Mazandaran, and Qazvin.
Kurdistan, autonomous in Iraq and Syria, will secede from Iran and take with it Luristan, forming the Free Republic of Kurdistan. Turkey will not be affected.
Turkmenistan will take half of Khorasan.
Baluchistan will separate from Iran and Pakistan and form its own state, Iran's Persian Republic will fight an intense war allied with Pakistan that will end with a UN Ceasefire.
Hormozgan and Khuzestan will become the Persian Gulf Emirate.
What will be left of Iran is a husk, robbed of resources and primed to be a pipeline state with no real power to stand in the way of Western interests.
And this is ALL possible due to Iranian lack of solidarity and our tendency for betrayal.
