Because, my friend, the news that you here is just the most noteworthy of the daily stuff that goes on in Pakistan. That is hardly average. I'm an Indian, I spent 4 years in Guwahati, Assam. That city has a reputation for terrorist violence, and the region (the Northeast) is known for atrocities committed by the Indian Army. But the only reason I saw anyone from the Army? There was an outpost in our campus (when the reason for the campus existing in the first place was the terrorists). But when I go home, I'm astonished by the chasm between reality and what the people imagine. For the very same reasons believe that most Pakistanis have at least seen AK 47s, I could believe that the US is a land of hurricanes.
