Indians are so quick to gripe about allegations against India, yet they have no qualms of harping the Pakistan mantra all the time.
Wrong. There's a large difference between what we say and what you say.
We usually blame the terrorist organisations ( which i really hope are not under the pakistani government). There are hardly times when we blame the pakistani government directly. We point at groups like Lashkar E Toiba , Hizbul , at times ISI because it has a history of relations with these groups(hopefully not now)
On the other hand , all attacks in pakistan are attributed directly to the indian government and RAW. Within like half an hour of the lahore attacks , the police seemed to be sure that these attacks had indian links. Even unprofessional indian channels take more than 2 days before pointing at pakistan
