"'War' is about people, war between people, lovers, war between religions - Catholics and Protestants, war in Politics. War is about struggle, conflict and realisation. So there is a theme running through the songs but it is definitely not a concept album. We really wanted to make every song different, as far away from what people expect from us, I think there are only two songs that people will know as U2."
- Bono on War, 1983
