Two incredibly low blows, although I suppose this way you've made your isolated point of view very clear.
> Moreover, both these neighbors are ganged up by their mutual animosity of India.
Another way of saying this is they've been successful in maintaining strong ties via diplomacy and trade, to the benefit of their peoples.

There have always been options; some of which India has rejected themselves, arguably leading to the souring of other international relations. This weapons test will hopefully lead to condemnations and repercussions, direct or indirect.
For example, I would welcome the IRSO being excluded from further policy-making as part of the Inter-Agency Space Debris Coordination Committee (IADC).
