Tectonic shifts in international affairs and in political and economic conditions within the United States call for reconsideration of the first principles of American grand strategy—the fundamental tenets guiding the nation’s statecraft. The global landscape is fast changing due to the ongoing diffusion of wealth from the West to the rest and the social awakenings taking place in the Middle East and beyond. At home, Democrats and Republicans are locking horns on most foreign policy issues and on how to control debt and stimulate growth; the resulting political stalemate risks compromising the purposeful exercise of U.S. power and eroding the economic foundations of national strength. Meanwhile, the wars in Iraq and Afghanistan and a shrinking defense budget have diminished the political appetite for sustaining the full portfolio of America’s global commitments.
