There is no tilt towards India. It's an imaginary idea that exists in Pakistan only, due to your obsession with that particular country.
Iran had a 10-year deal with India to develop Chabahar, signed by a treasonous c*nt called Rohani in 2015, which fortunately ended in 2025 and was not renewed.
Besides that, Iran had amicable relations with India before Modi came to power. Pakistan had stable relations with India in that period too. Both countries wanted to create a joint pipeline ("Peace Pipeline", also known as IPI). Modi has been a huge set back for India.
Whatever you said about KSA-Pakistan relations, also applies to Iran-India relations. Iran has never been hostile to Pakistan. Iran also has been very consistent on the issue of Kashmir. Probably one of the few Muslim countries in the world that has done that.
