American security policy and NATO's future

NATO remains the United States’ principal instrument for shaping the security environment in Europe. It acts as a long‐run hedge against a possible resurrected Russian threat to the continent and to dampen the prospects for the renationalization of military and security policies in Europe. The United States faces formidable challenges to ensure the viability of NATO after the Cold War. Washington must be prepared to engage in a grand balancing act on several fronts to perpetuate the Alliance. It must support NATO enlargement to move the Alliance's geopolitical center eastward, but not to territory that would practically indefensible in the event of a resurgent Russia. Out‐of‐area operations will preoccupy Alliance attention in the near‐future, but too great an appetite for undertaking peacekeeping missions might over time substantially erode the Alliance's ability to deter or withstand the political and military pressure from a resurgent Russia or major power or coalition on the outlying areas of the Eurasian landmass.
