Mary Kaldor's 
New and Old Wars has fundamentally changed the way  both scholars and policy-makers understand contemporary war and  conflict. In the context of globalization, this path-breaking book has  shown that what we think of as war - that is to say, war between states  in which the aim is to inflict maximum violence - is becoming an  anachronism. In its place is a new type of organized violence or 'new  wars', which could be described as a mixture of war, organized crime and  massive violations of human rights. The actors are both global and  local, public and private. The wars are fought for particularistic  political goals using tactics of terror and destabilization that are  theoretically outlawed by the rules of modern warfare. 
Kaldor's  analysis offers a basis for a cosmopolitan political response to these  wars, in which the monopoly of legitimate organized violence is  reconstructed on a transnational basis and international peacekeeping is  reconceptualized as cosmopolitan law enforcement. This approach also  has implications for the reconstruction of civil society, political  institutions, and economic and social relations. 
This third  edition has been fully revised and updated. Kaldor has added an  afterword answering the critics of the New Wars argument and, in a new  chapter, Kaldor shows how old war thinking in Afghanistan and Iraq  greatly exacerbated what turned out to be, in many ways, archetypal new  wars - characterised by identity politics, a criminalised war economy  and civilians as the main victims. 
Like its predecessors, the third edition of 
New and Old Wars will be essential reading for students of international relations,  politics and conflict studies as well as to all those interested in the  changing nature and prospect of warfare.
