West hopes to change regime in Iran, demilitarize and dismantle it.
Their plan:
1) Israel decapitates Iranian leadership by killing top generals and key officials
2) Israel destroys key infrastructure of Iran by targetting oil, gas, water, electricity
3) Israel absorbs most of Iranian ballistic missiles and after Iranian missile arsenal is exhausted US+UK+Germany+France+Italy enter the war
4) pro-Israeli coalition destroys Iranian civilian infrastructure, industry, government buildings with a huge bombing campaign that paralyzes Iran
5) After Iranian leadership decapitated, infrastructure destroyed, governance dysfunctional and ballistic missile arsenal exhausted, Western agents in Iran will try to create chaos and get anti-Islamic Republic Iranians to the streets for the purpose of toppling Iranian government.
Meantime Iran will destroy Israeli economy, oil infrastructure of the Persian Gulf region and mine the Strait of Hormuz.
Iran will mobilize Basijis to suppress pro-Western rioters and ethnic nationalists while the West will try to disrupt command and control structure of Basij through decapitation strikes and activation of double agents.
