Iran-Pakistan relations are a real mystery to me. When terrorists killed 14 security personnel near gwadar, they had come from and went back to iran. Similarly Uzair Baloch had an Iranian passport. Kulbhushan was operating from Iran and I find it extremely hard to accept that Iranians were unaware of his acgivities. I read somewhere(don't know if its true) allah nazar baloch was until recently in iran and was forced out due to pakistani pressure on iran. Similarly sectarian target killers according to ctd karachi had got training in iran. Similarly i think it was some officer from FC balochistan who said iran wasn't cooperating with fencing. Then their is iranian oil smuggling. Their president on Indian visit praised Indian 'diversity' and they never mention Kashmir (by the way what's their official position on Kashmir). I read a former Indian diplomat that Iran has helped India in the past relieve pressure on Kashmir issue from the oic platform.
Our government on the other hand doesn't give us a clue if all of this bothers them at all. I can understand if the establishment is dealing with all of this behind the scenes but that's my hunch.
