Actually Pakistan and India both can be good friends, and prosper amazingly if they work together. The problem is the inner factions of these two countries who dont like it to happen. And these inner factions are the extremists which is present in India in the form of BJP, RSS and so many others and in pakistan in the form of Jihadis. They both serve the same purpose.. i.e. increase the animosity between two countries and keep them away. Thats why they exploit the situation like one in Mumbai. Otherwise people in both countries are innocent and peaceful. They have their own problems and instead of all these contraversies, they should be given their solutions to live happily and peacefully. But right now, it just looks like a wish far from reality!
I have few Indian friends here, who thinks the same, and yes, it is the right approach to achieve prosperity and peace (P&P) between the two nations, but this P&P will bring education and awarness amoung the people, which will eliminate the current generation of political approach, so why would these politician would do something which can eliminate them.
