Pakistan is a great place to be. Just dont go to border areas, Balochistan these days. There, the situation is uncertain. As for cities, they are quite peaceful. If I compare which of the cities are safer, then Lahore & Islamabad are much safer than Karachi. In Karachi political violence does break out some time, but it is not dangerous still.
If you visit Pakistan, you will be surprised to see total opposite of what you see in the newspapers. People are hospitable, but you will also see shopping malls, restaurants and other places crowded with people. As I visit there every year, I see new projects, new roads and new advancements every year.
Being a Pakistani when I read newspapers, I fear the whole country is on fire. Its the way newspaper business is I guess. They just want to give a stereotypical view of the country. The view the people are familiar with.
