Quite easily. The claim was that India was never the aggressor, not that all the aggressions were justified by some extenuating circumstance or national interest or whatnot. The "never the aggressor" claim clearly doesn't hold for https://en.wikipedia.org/wiki/Annexation_of_Portuguese_India. I'm not saying that India shouldn't have done it, note, just that India has in fact used military aggression when it felt its national interests warrant it, which is perfectly normal for nation-states.

We can have a long discussion about whether we expect such situations, where national interests are judged to warrant military aggression, to arise in the future. But that's a discussion that should be had, not dismissed by appealing to untrue claims about history.

> It was the only time India had to resort to military action

Did you stop reading halfway though my comment?

Seriously, I think India has done a quite good job, as nation-states go, at not attacking its neighbors. But claiming things like "it was the only time India had to resort to military action" just doesn't look like it's supported by the facts to me. "One of the few times", yes.
