True. India today is much stronger than it was 30-60 years ago.
But believing that prosperity would bring Unity is a fallacy.
On the contrary prosperity has always brought wars and divisions from the time of Mahabharata to Ambanis.
US survived the breakup of USSR not because it was prosperous but it was successful in creating a new enemies.
Creation of EU, EURO and EU's détente with Warsaw pact countries were direct threats to NATO and the unity of US but it had AK, IS, NK, Russia, China etc. come to it's rescue.
India and Pakistan are not joined. to the Hip two different nations which took diverging paths post independence. The most immediate threat that comes from the "Supposed" breaking up of Pakistan is
1. Syria Like Situation
2. Refugee Crisis is neighboring Countries.
3. Nukes Going Rouge
And if you believe that the purpose of a state is the constant existence of an adversary, Then don't worry we would be having more than our plates full with China (This article sums up where Sino-Russia ties are headed).
The point that prosperity always brings about divisions then, makes me worry, we shouldn't prosper in first place ? We will have plenty more adversaries. Prosperity always brings more friends and more enemies. So the game will continue.
LOL... why ?
Syria like situation. Migrant Crisis.
