Pak is way stronger than iran in all areas just need confidence but i am not saying we should fight with iran but we should not destroy old relationships for sake of one country .Perhaps for token force in KSA, but a full mobilization of the Pakistan Army for a war in Syria? If the targets will be Shia, then this might sour relations Pakistan has with its contiguous neighbor and regional heavy weight, the Islamic Republic of Iran. The point is that Pakistan has to balance her interests and her startegic links between Iran on he hand and the KSA on the other.
