according to the Rules Based International Order (tm) yes

Just like USA attacked stronghold of Osama Bin Laden which was in a country far far away (can't remember which country), India is just sorting out known terrorist training camps in its neighbourhood.

I suppose it was equally illegal for USA to kill Osama in (can't remember which country).

Did you read what I wrote? Pakistan has covertly supported terrorism. Pakistan did not share intelligence with India during the Mumbai attack. Independent intelligence from other countries confirmed Pakistan's role in the attacks.

India did not target any Pakistani military sites. It claims to have targeted LeT and Jaish e Mohammed bases. Pakistan still shields many internationally recognised terrorists.

You're naive if you think Pakistan is 'governed'. It is a military masquerading as a government. Again, read. Maybe look up the Mumbai attacks and Pakistan's role in them. Look up how Hizbul Mujahideen foiled indigenous Kashmiri militant groups like the JKLF and ratted them out to the Indian army because they weren't loyal enough to Pakistan. It's an inter imperialist conflict. Class war doesn't play out on the country level. I don't support war, or warmongering.
