The US eschews multilateralism and prefers unilateralism.  Rather than working through international institutions and gaining the consent of the international community as a ‘benign’ hegemon would be expected to do, the United States far too often undermines multilateralism and exercises its power unilaterally. President Clinton’s military interventions during the 1990s, George W. Bush’s unilateral launching of the Iraq War, and President Obama’s use of covert drone attacks illustrate this propensity to shun multilateralism in favour of the “imperial logic” of unilateralism.[28] Indeed, since the end of the Cold War the United Nations has frequently been ignored or devalued as an institution by America. Most American policymakers are what Robert Kagan refers to as “instrumental multilateralists.” They engage with multilateral institutions for pragmatic reasons, but act unilaterally when it serves the interests of the United States. This is in contrast to many European leaders, who Kagan describes as “principled multilateralists” that are interested in multilateralism as a cornerstone of world order.[29]  [28] Ikenberry, John G.
