About seven decades ago, the colonials who swept through Asia in the eighteenth and nineteenth centuries and earlier started their retreat. They had lost so much money fighting each other over their spoils during the World Wars that they could not afford the upkeep of their colonies.
One of the aftermath of the colonial rule in Asia was the formalisation of national boundaries. The Indian subcontinent was split into India and Pakistan( West and East, which later disengaged from the West and evolved as Bangladesh).The angst that started during the Partition of the Indian sub- continent generated violence that took more than 200,000 to 2 million lives. The figures remain disputed.
