Thank you for expressing your 'doubt,' demonstrating exactly the point I wished to make, concerning insularity. You really do have no idea.
Pakistan is a Commonwealth country. It enjoys significant historical, social, political, economic, cultural, academic and sporting ties with other Commonwealth countries. Further, there are numerous expat Pakistani communities throughout the Commonwealth. As such, there is a great deal of familiarity with Pakistan in our societies.
Because they're people we know, not just "A-rabs that should be 'nuked into a great big Middle East glass parking lot." And, more to the point, Khan is not just some random Muslim that your society is quite happy to intern in a concentration camp in occupied Cuba, to us.
Here's an example: I've never met Imran, but a member of my immediate family has. I've never met Pervez Musharraf either but we did exchange a "hello" to one another when our gazes happened to meet in an Auckland hotel lobby. He was there to attend the Commonwealth Heads of Government Meeting. I was heading to the bar, wearing a tshirt, shorts and jandals.
You might like to put this to the test. Here's how: find the nearest Japie/Convict/Kiwi/Pom in your vicinty and say this:
You'll get back "Khan, Younis, Akram, Bhuto." Betcha.
Now try that on one of your compatriots. You're likely to get a visit from Fatherland Security.
