Abstract
During the 2001–2009 period when American foreign policy was internationally unpopular and perceived as unilateral, many states strengthened their security cooperation with the United States and facilitated the reach of the us military. This behavior spans a range of actions along a spectrum from reaffirming traditional alliances to far more subtle forms of alignment. This pattern is in large part driven by the actions of regional powers such as Russia and China whose rising power pushes neighboring states to seek the assurance of the United States, and it has distinct implications for the endurance of American hegemony. As those regional powers seek to expand their influence, secondary states may increase their contributions to the maintenance of American hegemony, thus helping to extend it well into the future. They are less prone to do so, however, if the United States follows a strategy of restraint that calls into question its willingness to defend its hegemony. Therefore, a policy focused on maintaining American military preeminence and the demonstrated willingness to use it may be what sustains the cooperation from second-tier states that helps to maintain American hegemony.
