Cover art for Year of tha Boomerang lyrics by Rage Against the Machine

Actually, the song is based on a speech by Franz Fanton, an Algerian revolutionary who fought in the anti-imperialist war against France. He claimed that there will be a "Year of the Boomerang" in which all of the misery and inequality that imperialism created will come back and hit global capitalism on the face.
