Trump and the remaking of American grand strategy : the shift from open door globalism to economic nationalism “A brilliant impeccably researched must read analysis of the shifting tectonic plates of American power.” — Inderjeet Parmar Professor of International Politics City University of London UK This book offers a comprehensive explanatory account of Trump’s foreign policy by assessing its nature determining the extent to which it broke with the policy of preceding presidencies and explaining this shift’s genesis. We argue that Trump has succeeded in remaking America’s grand strategy by unmaking its long standing strategy of what we call Open Door Globalism a strategy of economic expansionism through the promotion of open markets globally and its institutionalization into a US led liberal world order. Trump has broken with Open Door Globalism in probably lasting ways by adopting an outlook and strategy of neo mercantilist economic nationalism based upon an ‘America First’ redefinition of US sovereignty and national interests. Explaining this Trumpian shift in US foreign policy we focus on the social sources of Trump’s foreign policy making elite’s agency analysing its embeddedness in elite networks and within the changing global and domestic context. The latter coupled with a crisis of established elite power also indicates why Biden has not returned to Open Door Globalism but doubled down on aspects of the Trumpian economic nationalist break.
