To declare oneself a conservative in American foreign policy is to enter immediately into a fractious, long-standing debate. Should America retreat from the world, deal with the world as it is, or try to transform it in its own image? Which school of thought - traditionalist, realist, or neoconservative - is truest to the country's ideals and interests? With the dramatic shift in American foreign policy since 9/11, these differences have been brought into stark relief, especially by the Bush administration's decision to go to war in Iraq. This book brings together the most articulate and influential voices in the debate among conservatives over the tactics and strategy of America's engagement in Iraq. Its contribution run the gamut from protests to second thoughts to full-throated endorsements, and represent a vivid sampling of the ideological currents likely to influence the Bush administration in its ongoing efforts in Iraq and the wider Middle East.
