This song is about Bono's time with Amnesty International in El Salvador during the 1980s. There, Bono witnessed the firebombing of a small village by the US military. It is said that Bono told The Edge to "put El Salvador through an amplifier". This is easily one of U2's most political songs, and is usually played along with a message against political conflicts and violence. When U2 performed in Boston in 2001, they played "Bullet the Blue Sky" accompanied by a video of the president of the NRA at the time, Charlton Heston, who said, when asked about his agenda for the NRA, "Well, here's my credo - there are no good guns, there are no bad guns. A gun in the hands of a bad man is a bad thing. Any gun in the hands of a good man is no threat to anyone, except bad people." This is followed by a video of a young girl getting into a bag and pulling out a handgun.
