I cannot believe that Iran was unaware of all these RAW activities against Pakistan...
But in the end its all about "National Interests" ....
Its a "Lamha-e-Fikriya" for those Pakistani Shiites who always defended Iranian activities.... From Kulbhushan Yadev statement, its evident that RAW was funding Nationalist Baloch Terrorism and Sectarian Terrorism as well (which is against Pakistani Shiites).... And Iran silence on RAW activities shows that indirectly they were aware of this Shiite Killings and Sectarian Violance but due to National Interests they were silent ( if not supporting) on RAW....
Its a very serious issue for Pakistan as well.... If Iran was directly/indirectly involved in this issues than we need to deploy our Army on Iranian Border as well...
