Re: Proof
India-Pakistan-etc is a UK blunder as well.
Nope. Deliberate. The Brits thought, not wholly unreasonably, that a couple of former provinces full of restive muslims would be a nice expression of their everlasting gratitude towards Ghandi for kicking them out.
When that didn't work as planned, they probably backed Muhammad Zia-ul-Haq all the way, after all, there has never been a Sunni Zealot that "the West" didn't like!
