Pakistan is a child of the two-nation theory. This is not a matter of geography. Its premise is that Hindus and Muslims belong to separate nations. Jinnah reiterated a million times that living with Hindus was submission to Hindu tyranny and sneered at Maulana Azad when the latter insisted that a secular multi-faith state was not only possible, but desirable.
This is the basis for every Pakistani’s conviction that the Kashmir valley is rightfully a part of Pakistan, and Indian rule in Srinagar is ruthless colonization.
