India Will never try to Integrate Bangladesh Or Pakistan Into what is now India, Because FRANKLY, there is nothing worthwhile in these Nations, I mean Like OIL, Or a Developed Industrial Base or other Economic Incentives. India would have Collapsed If It tried to Integrate Bangladesh in 71, We couldnt handle the Influx of Refugees, Do you think we could have Handled a Whole New Country?????
At the moment I shall only limit my answer to this portion as rest has been discussed in great detail and you can go through that on this forum.
Considering the sixty year history of the three nations one comes across a very interesting fact. At the time of independence Pakistan and then in 1971 Bangladesh had almost nothing to start. They were without basic industrial structure and had to start from scratch.
Considering that and present day scenario I do believe it is Pakistan and to some extent Bangladesh that have really made progress unlike India which had decent set up and should have progressed more than it did.
Pakistan neither had decent industrial base, nor edcuational institutions, nor infrastructure set up and yet it has progressed well.
Unfortunately it would become a very long post that is why I am only writing a very brief summary.
