Islamabad is crawling with military holding machine guns. A hotel I stayed at once while working there had a machine gun armed soldier on every floor monitoring the halls from the elevator door area, and one pacing around the pool area at all times. Do they have that in London or Paris? It seems to depend on your definition of "safe" because those guys wouldn't be needed in such numbers if it was actually safe.
