Isn't referendum the only way to confirm if its a minority or a majority that wants to choose their own destiny? In which book of democracy/civilization does it state that people lose their democratic right of choice, if they wish to choose a theocratic state? what difference does it make if Pakistan is a secular or theocratic state? and What difference does it make if Pakistan and Bangladesh merge or not? explain me the logic of your statement.
Also isn't the choice of the people the very reason that India invaded Jungarh and did a referendum there. wasn't the will of the people the very excuse that India use to invade Hyderabad? Was't the invasion of Goa also done on the same pretext?
Going by history it seems India is all for peoples choice except when it comes to Kashmiris. Hypocritical isn't it?
