What is terrorism? Can it ever be the right thing to do? Who is really responsible for terrorism? Should governments never negotiate with terrorists? And how can terrorism be stopped? This study delves into what underlies terrorism, what in some cases justifies it on ethical grounds, and how terrorism might be dealt with successfully. Rather than assuming from the start a particular point of view about terrorism, the book engages the reader in a series of critical discussions that unveil the ethical problems underlying terrorism. What terrorism demands, from Americans in their power above all, is moral intelligence. The author applies an articulated morality to terrorism and to civil disobedience. It links these with secession and aims to makes philosophy work in the world we now know.
