Mr. Chawla, It was the matter of safety of more than 150 passengers . Mind you, plane was in hostile country Afghanistan and was governed by Taliban. What could Govt do? How could NSG react? Check out Footage ? Taliban had pointed anti aircraft at Indian Plane and runway was blocked by tanks. Cant you make out the compulsions of Govt in this situation.
You can watch National Geography --They have showcased this Hijacking lot of times. In fact worse was done in case of Rubya Sayed, daughter of Mufti Sayed then Home minister of India. 5 Hardcore terroristes were released in exchange of 1 Girl--daughter of Mufti Sayed.
So shut your mouth and dont follow any ideology blindly
