If a hostile regime does take over, Pakistan (possibly in coordination with China and Turkey) should militarily intervene (create counterterrorism buffer zone in Sistan Balochistan with the end goal of uniting it with Balochistan Province).
The Americans won't spend 20+ years occupying Iran, they'll just destroy the nuclear program, economy, military, install a puppet regime, and leave. The Israelis will be put in charge of Persia afterwards. We have to take action to weaken the new Israeli puppet regime.
We CANNOT afford to have Mossad in Balochistan. They are not incompetent duffers like Indians.
