Facilitating access to asylum and other forms of refugee protection for the millions displaced by mass atrocities in Syria and Iraq is essential to the implementation of the international norm of the Responsibility to Protect. This responsibility, however, has been disproportionately shouldered by several states in the Middle East and Europe. This article explores the challenges associated with refugee responsibility-sharing in the context of RtoP and draws on work in climate justice and political realism to articulate a framework for integrating (...) culpability as a key criterion in allocating states’ responsibilities to protect refugees. An empirical and normative assessment of U.S. responsibilities to protect refugees in the cases of conflict-induced displacement in Syria and Iraq outlines several potential paths of culpability. The article ultimately argues for greater attention to culpability, equity, and legitimacy within the discourse surrounding RtoP and refugee protection. The article also advocates linking the benefits of refugee responsibility-sharing with states’ national interests and highlights several such links with regard to U.S. responsibilities in Syria and Iraq.
