Kent on the Interwar Development of American Economic Sanctions

Andrew Kent, Fordham University School of Law, has posted The Pre-History of Modern Economic Sanctions, which is forthcoming in Constitutional Commentary:

This review essay examines the historical emergence of modern economic sanctions through the lens of Professor Nicholas Mulder’s outstanding 2022 book, The Economic Weapon.  It then supplements Mulder’s account with a fuller treatment of developments in the United States between World War I and the start of World War II.  The emergence of modern sanctions depended on transformations in international and domestic law, international diplomacy, state administrative capacity, and moral and legal understandings of coercion against civilian populations.  Mulder shows that these changes took shape principally during and after World War I, and focuses his monograph on Britain, France, and the League of Nations, with some attention to the United States.  This essay supplements Mulder’s transnational history with a more detailed account of U.S. law and institutions in the first four decades of the twentieth century.  In the United States, developments during World War I and the interwar period—including the Trading with the Enemy Act, export-control measures, debates about Congress’s neutrality statutes and the merits of using American economic coercion against fascist and expansionist powers, and a growing acceptance of broad executive discretion in foreign affairs—worked together to help create a rudimentary but recognizably modern sanctions regime by the time the United States entered World War II.  The essay highlights the U.S. constitutional questions raised by these developments, including questions about the nondelegation principle, the scope of presidential power and Congress’s foreign and interstate commerce powers, and protections for individual constitutional rights.
