From a demographics perspective India's future looks good with a very large population of young. China's isn't looking all that bright courtesy of their 1 child policy. But in a few decades it will be India's turn to face the music and at that time, if our neighbors have a demographic advantage on us (and we have two very pesky ones - porkistan and kangaldesh), we will be in a very dicey situation. For us to avoid that future, and I am not sure what plan our great governments and administrators are coming up with to address the demographic decline we will likely phase (i doubt the thought even enters their minds), the only option is to ensure our pesky neighbors don't grab an advantage, they need to be broken up.
I don't know if Kangaldesh has any form of internal separatist movements to take advantage of, but kangalstan has some and we need to push it. We have to break up that country so that in the future they arent capable of leveraging their demographic advantages. We cannot afford to wait and watch. The only way to keep kangalstan in a perpetual state of undonkeymated ikanamee is to break it up. Balochis need to get their own country not just an autonomous region inside Kanglustan. And if the telebunnies can take over the pashto regions across the Durand line, that would be the best possible outcome for us. After that, a downsized Pakistan with a new hostile neighbor (Balochistan) and continued internal strife in Gilgit Baltistan and utterly incompetence in Islamabad will ensure India will ride out what ever demographic problems we will face.
I won't consider Nepal, Bhutan and SriLanka as pesky neighbors in this regards.
Myanmar has a potential to cause issues in the north east, but that is more of being a staging point for insurgeries in north east and I don't see any active interest by their junta or former demo govs to leverage the situation to their favor. They have enough issues as is without having to take on India now or in the future.
Kangaldesh is my big concern, we don't have anything to leverage vis a vis to cut them down into multiple states. They have the threat of getting drwoned but so do our coastal areas and if and when they do drown, their populations will flood our lands and that is a dangerous situation for us. What we need is to break up kangaldesh and I just don't see any way of doing it. I don't mean occupy portions of Kangaldesh, that will never work in our favor what with international pressure and the internal guerilla resistance they will mount up.
Maldives will be another thorn on our side but they cannot influence us in terms of demographics, just being a thorn by providing the Chinese military access to our immediate neighborhood. The one way we can counter them is to continue to foster good relations with them, there are still a significant portion of Maldives people who support India.
Anyway, my point is, break kangalstan soon. We cannot let this opportunity slip by. Balochis need to breakaway as a separate country and telebunnies need to man up and take the pushto lands now.
