I'd strangle him and piss on his corpse the first chance I get.
Pakistan is like India-lite but actually thinks as if they have the tendency to compete with us. The lag behind India in just about everything that matters - talent, education, technology, economy...you name it. But the losers still think they are a match for us. It's a well known fact that Indians are infinitely more socially respected and qualified than Pakistanis which also seems to really get on their nerves. I think the heated rivalry has more to do with the fact that Pakistan was the reason why India was crippled after independence in 1947.
Most of India's richest fields and natural resources went to Pakistan's side of the border. Not to mention the fact that the founder of Pakistan - Muhammed Ali Jinnah, was a class A a**hole. He was the one who needlessly wanted a separate state for Muslims, even though after partition India's Muslim population far outnumbered Pakistan's. That is also one of the reasons why even the Muslim population of India detests Pakistan for scattering the Muslim population between East and West Pakistan (which is now known as Bangladesh) that consequently made Indian Muslims easy targets of radical Hindu nationalists (in attacks such as the demolition of the Babri mosque, a 400 year old monument) in many communal riots. Plus, the Indo-Pakistani wars of 1965 and 71 didn't really help the bitterness either.
Of course, I have known some truly great people who are from Pakistan - persons who I honestly admire to no end. But then again, they are just as much an exception as they are exceptional.
