China doesn't belong on this list. Nehru's government was aggressively pro China. China returned the favour by invading Tibet and then attacking India [1].
If Mao hadn't done that, we'd probably be living in a Sino-Indian world order today. (India and China have surprisingly few fundamental geopolitical overlaps, the Himalayas neatly partitioning their spheres.)
Hmm, so in eastern Kashmir, in fact. Versus Tibet!
Your turn.
I see you had shifted the goal posts from being aggressor to "disproportionate response". My original comment said India has never been the aggressor and thanks for finally agreeing to that. I will not comment on the response being disproportionate or not, because that is just an attempt to derail the original conversation.
