We live in an age of asymmetric warfare. Huge armies no longer face each other on the battlefield. Instead heads of major powers and lone assassins (or martyrs) target each other to pursue their agendas. President Barack Obama felt fully justified in sending in US Navy SEALs to take out Osama bin Laden in Pakistan. This is the nature of modern warfare. When nineteen-year-old Gavrilo Princip assassinated Archduke Franz Ferdinand, heir to the Austrian throne, in 1914, he triggered the First World War. Few assassinations have had such devastating consequences, but political assassinations have always changed the world--often in ways that the assassins and their cohorts could not have predicted. The murder of John F. Kennedy left Lyndon B. Johnson free to escalate the war in Vietnam. However, the assassination of Martin Luther King, Jr., while not derailing the demands for African American civil rights in the US, did lead many to abandoning his commitment to nonviolence and adopting more radical means. There are forty-eight assassinations that changed the world in this book. Rest assured that in the coming years we will see many more.
