I have met a number of Pakistani Canadians in my life time, and I proudly declare myself a strong supporter of this demographic in Canadian society. They are hard working, intelligent, and when you get the opportunity to engage them in a thoughtful conversation it is often a rewarding experience. If more Pakistani people want to move to Canada, then I would support increasing the quota.
But to paraphrase Tom Hanks in Apollo 13, "Islamabad, you have a problem." The armed revolutionary movement in the north of your country has become rabid and needs to be put down. The problem spilled into the Swat Valley this year, and the Pakistani military responded with appropriate force. Pakistan has a very potent military, and the only chance NATO has of defeating this "insurgency" in Afghanistan hinges on Pakistan maintaining the offensive. When Benazir Bhutto was assassinated, I was very sad. When her obituary was featured in Time Magazine Jan 14, 2008, I not only purchased the magazine, I framed it and put it up on my wall to honour her memory.
To Pakistani Canadians who still have family in Pakistan, I would encourage you to go down to your local video store and look for copies of a North American classic called Old Yeller. Maybe send a few copies back home. This film is perfect allegory for your problem with the militant Pashtuns. You feel a natural kinship with them, and once upon a time they helped save you from harm, but once they become rabid and turn on you, they must be put down.
Old Yeller. Available at a video store near you.
