That's exactly how the Indians think. India's got a really strong state propaganda machine. They all believe they were very wronged by Pakistan, in these Mumbai attacks. Even though the facts are entirely to the contrary. Half a dozen men "taking over" a three-hundred room hotel, and the Indian security forces are unable to do anything for nearly a week, in the Mumbai incident.. the Indian security forces could have broken in and took over 90% of the hotel and the half-dozen people wouldn't even have realized, because it takes alot more people to cover 300 rooms. And they still blame Pakistan.
And then Pakistan has a "Mumbai attack" situation literally every month, some new blast, attacks on Mosques and things no Muslim would do, these things that Indians stage, but this doesn't factor in their psyche.
Just like 9/11, the Indian establishment stages events like Mumbai harming their own people to achieve their geo-political aims and make their enemy Pakistan look bad, and the Indians mindlessly follow the propaganda. And while their govt stages terror attacks in Pakistan as well, these people still believe that somehow Pakistan is wronging them, that it is Pakistan that is the aggressor.
