Lol wut? There was a terrorist attack in India and shortly after there was a small conflict for a few days. You must live in the la la land if you think it was a war. Now, I don‘t know the truth behind allegations that Pakistan was directly involved but it doesn‘t matter. Also once again, you are showing you have no clue about you are talking about. There are no Indian troops in Sri Lanka. Also Google says India‘s defence expenditure as a share of its GDP is 1.9%. Not at all a representative of a country that sacrifices economy for military.
A war is a war, and it can't be ignored just because it's short!
In a border terrorist attack, India blamed Pakistan before conducting a thorough investigation and even began mobilizing troops to the border. Is this what a normal country would do?
Is it what a peace-loving country would do to bomb homes in a neighboring country without hesitation?
Violating the Indus River Agreement, arbitrarily closing the upstream sluice gates and then suddenly opening them, causing flooding downstream, can be considered, without hesitation, a crime against humanity.
I don't have the time to go into detail about what India has done to its neighbors. You should learn about Sikkim's history yourself.
