Retired Col. Thomas Ehrhard, in his Center for Strategic and Budgetary Assessments study “An Air Force Strategy for the Long Haul,” wrote that the U.S. faces three primary existing and emerging strategic challenges that are most likely to preoccupy senior decision-makers in the coming years: “defeating ... Islamist radicalism,” “hedging against the rise of a hostile or more openly confrontational China and the potential challenge posed by authoritarian capitalist states” and “preparing for a world in which there are more nuclear-armed regional powers.”
