Who are terrorists? How do they justify what they do?

Award-winning author Milton Meltzer searches for answers as he puts terrorism and its practitioners into historical context. Asking moral questions more troubling than ever before, Meltzer shows that terrorism is as old as humankind and that it has been the tool of innumerable ideologies, religions, and ethnic groups, all over the world.

Originally published in 1983 as The Terrorists, The Day the Sky Fell has been updated by the author, with new chapters and a new introduction.
