Yeah.. Iran-Afghan. Not India-Iran-Afghan which was the talk of the decade in India during the Afghan War, with the India-friendly Karzai who faded into irrelevancy and Ghani who now sits in exile.Its INSTC where that I stand for International. Iran is improving its infrastructure for connectivity. i am not sure why you irritated by this trade route.
Iran-Afghan trade now $3b.
India conceptualized this concept and convinced Iran + Afghan puppets but once US sanctioned Iran, India realized it's neither a superpower nor a regional power and abandoned the project.
Once US sanctions on Iran expired, India tried again with that new corridor to Europe via Russia and Iran. Now Russia is heavily sanctioned by Europe and America, while Iran is probably going to war with a country who has military ties with India... LOLOLOLOL!
Why would I be irritated? I'm laughing at the idiocy of Indian strategic thinkers.
