You could argue that https://en.wikipedia.org/wiki/Bangladesh_Liberation_War#Indi... was an instance of Pakistan attacking first, but note that India was actively arming and training insurgents inside what was at the time Pakistan. So it's hard to claim that this is an instance of Pakistani aggression without at the same time viewing the fairly symmetric https://en.wikipedia.org/wiki/Indo-Pakistani_War_of_1965 as an instance of Indian aggression. Personally, I would consider the latter as Pakistani aggression, and the former as Indian aggression....
That's a bit of rewriting of history right there.
I suppose you will claim that India's involvement in https://en.wikipedia.org/wiki/Annexation_of_Dadra_and_Nagar_... was simply connivance and instigation by the government, not active participation by the Indian military? But https://en.wikipedia.org/wiki/Annexation_of_Portuguese_India was definitely the Indian military, not just random groups supported by the government.

It's also hard to say who was the aggressor in https://en.wikipedia.org/wiki/Siachen_conflict because both sides were acting basically equivalently as far as I can tell.
