Much has changed in warfare in recent years, with America now dominant on the international scene and terrorism the new enemy. In light of these changes, the need for moral grounding in military actions is a more pressing concern than ever. When it was originally published, Moral Issues in Military Decision Making reflected the concerns posed by nuclear stalemate and the lessons of Vietnam. In that highly-praised work. Anthony Hartle outlined the essential elements of the Professional Military Ethic created for American military forces. In this new edition, he reexamines the moral foundations for America's military leadership in the post-9/11 era. Considering world affairs since the first edition - the Gulf War, Bosnia, Afghanistan, Iraq, 9/11, and the emergence of the United States as an unrivaled military power - Hartle explains how these events have raised ethical issues that differ dramatically from those of the Cold War. He assesses how moral, legal, and psychological concerns have been impacted by the war on terrorism, homeland defense, asymmetric warfare, the proliferation of American military interventions, and the UN's role in peacekeeping operations.
