The New Wars - Hardcoverby Herfried Mnkler (Author) This important new book deals with the changing nature of war in the post Cold War era and the emergence of new forms of warfare in which warlords, mercenaries and terrorists play an increasingly important role. In the modern era, warfare came to play a crucial role in the formation of states, whereas the new wars emerging at the beginning of the 21st century have mostly gone together with the failure or collapse of states.
