There is a possibility that India is in cohorts with Israel for regime change in Iran. If the regime changes then there is more to profit from Chabahar than under the current regime as it would then be accessible to the Western powers and takeaway the shine from Gwadar. Also, while Iran's regime has been open for all sorts of bad businesses with India - including housing RAW agents and BLA to destabilize Gwadar - it has not given any support to India on international level against Pakistan. In fact, in recent years Iranian regime has been vocally support Pakistan, including on Kashmir. Finally, Hindutava goons would love to do such a thing to a regime that has Islam as its identity. Guess Iran needs to reassess its diplomacy if this war resolves in status quo ante bellum.
