Is there an emerging left-wing foreign policy in the United States?

Abstract

Is there a left-wing foreign policy emerging in the United States? The rise of an energized and assertive left wing of the Democratic Party, and a receptive constituency within the electorate, has opened space for new political possibilities at home. In the foreign policy realm, leftist internationalism is making compelling arguments about new directions. However, there are limitations to the possible realization of a left-wing foreign policy in the US. While candidates like Sanders and Warren are distinctive in a left-wing foreign policy worldview, the practical implications of their foreign policies are consistent with post-Cold War practice. There are two important exceptions: in trade policy and in their positions on the use of military force. Here they mark a sharp break from the liberal internationalist mainstream. This paper outlines five broad principles of left internationalism, assesses the foreign policy positions of leading Democratic candidates for the 2020 nomination, and explores the long-term prospects of left-wing foreign policy in the US after 2020.
