Whither the US empire? Despite Washington's military supremacy, its economic foundations have been weakening since the Vietnam war - accelerated by the great recession and credit-rating downgrade - and its global authority dented by the quagmires in Iraq and Afghanistan. In this accessible, punchy text, Vassilis K. Fouskas and Bülent Gökay intervene in the debates that surround the US's status as an Empire. They survey the arguments amongst Marxist and critical scholars, from Immanuel Wallerstein and others who argue that the US is in decline, to those who maintain that it remains a robust superpower. By explaining how America's neo-imperial system of governance has been working since WWII, Fouskas and Gökay link the US's domestic and foreign vulnerabilities. The Fall of the US Empire argues that the time has come to understand the US empire not by its power but by its systemic vulnerabilities of financialisation, resource depletion and environmental degradation. Its informed and accessible style will have wide appeal to students looking for an introduction to these issues.
