"40 Years" by Paul Hardcastle is a commentary on the destructive potential of nuclear weapons and the consequences of their use on the world. The song reflects on the events of the past 40 years, including the development and use of atomic and hydrogen bombs, and questions if there will be a world in another 40 years. The lyrics reference the first atomic bomb test in 1945 and the subsequent arms race that led to the creation of more powerful bombs. Hardcastle criticizes the idea that such weapons would bring about peace and suggests that their use would only lead to destruction and loss of life. The song also touches on the topic of nuclear disarmament and the need to move away from the threat of war and towards a peaceful world. Overall, "40 Years" serves as a reminder of the dangers of nuclear weapons and the importance of working towards a world free from their threat.
