I think this song expresses a feeling that many people in the Middle East are experiencing right now. The USA is carrying out drone strikes against suspects of terrorism but causes way too many civilian deaths. The scary thing about predator drones is that you can never see or hear them coming.You could randomly become a victim if you just happened to be near a group of Taliban or if you just happened to be mistaken for a Taliban soldier yourself. Victims of drone strikes now claim that they fear to go out under blue skies because they know that drones don't fly during cloudy days.
