I don't know.. My first waypoint for the Pakistan squeeze would be Financial action task force blacklisting Pakistan, because except for India and modi's insistence, neither the US, nor Russia,. China or Saudis want to blacklist them. Remember, for all the trouble that Pakistan has caused the US including having its soldiers killed, the US has put no economic squeeze on pakistan. It has only stopped aid. Only a tenth of sanctions faced by Iran would have completely crippled Pakistan's textile export and remittance driven economy.
If Modi had any real backbone, he would have suspended iranian oil imports only in return for a *censored* blacklist of Pakistan(although US has hinted Azhar was the trade,.. I have my doubts). Also, India is suddenly getting all chummy with turkey, with Turkish deputy minister of foreign affairs visiting in may, and Turkey's anadolu shipyard picked for the 2.1 BN fleet tanker project.
Turkey’s TAIS picked for Indian Navy fleet support ship design
Also Jaishankar called Turkish foreign minister yesterday.
So, things are taking an interesting turn. If you remember Turkey was the only member to have voted against grey listing Pakistan..
