The first step in any 12-step imperial-overstretch recovery program would involve accepting the fact that American power is limited and global rule an impossible fantasy. Accepted as well would have to be this obvious reality: like it or not, the U.S. shares the planet with a coterie of other major powers -- none as strong as we are, but none so weak as to be intimidated by the threat of U.S. military intervention. Having absorbed a more realistic assessment of American power, Washington would then have to focus on how exactly to cohabit with such powers -- Russia, China, and Iran among them -- and manage its differences with them without igniting yet more disastrous regional firestorms. But for any of this to happen, American policymakers would first have to abandon the pretense that the United States remains the sole global superpower -- and that may be too bitter a pill for the present American psyche (and for the political aspirations of certain Republican candidates) to swallow. From such denialism, it’s already clear, will only come further ill-conceived military adventures abroad and, sooner or later, under far grimmer circumstances, an American reckoning with reality.
