In this fourth in a series of columns, Illinois Law professor Lesley M. Wexler explains how the U.S., Ukraine, and Cluster Mine Ban Treaty parties can reinforce norms against cluster munitions use and enhance civilian protections, given the controversial decision of the Biden administration to supply Ukraine with these munitions. Professor Wexler argues that the U.S. and Ukraine should take several steps to bolster their public commitments to keeping civilians safe from cluster munitions including: both joining the Cluster Mine Ban Treaty or negotiating international restriction on high dud rates under the Convention on Certain Conventional Weapons; Ukraine operationalizing its assurances about use, conducting investigations into past unlawful use, and implementing Civilian Casualty Tracking Analysis and Response cells; and the U.S. monitoring and reporting on Ukraine’s compliance, tightening restrictions on the munitions use, and ceasing transferring cluster munitions once conventional artillery becomes more widely available.

In this third in a series of columns about the Biden administration’s transfer of cluster mines to Ukraine, Illinois Law professor Lesley M. Wexler explains why, even in the absence of a clear international violation, the transfer implicates the norm against cluster mine use. Professor Wexler describes cluster mine norms before the U.S. transfer to Ukraine and explains why, in her view, the transfer is problematic.

In this second in a series of columns discussing the U.S. transfer of cluster munitions to Ukraine, Illinois Law professor Lesley M. Wexler discusses the domestic issues for the United States and international law issues for Cluster Ban Treaty members. Professor Wexler also addresses arguments about Ukraine losing the moral high ground and weakening the alliance.

In this three-part series of columns, Illinois Law professor Lesley M. Wexler comments on the recent news that the Biden administration will be providing cluster munitions to Ukraine. In this Part I, Professor Wexler explains what cluster munitions are, why the Biden administration decided to give them to Ukraine, the potential impact on civilian populations, and the international law issues the United States and Ukraine face as a result.

Illinois law professor Lesley M. Wexler argues that based on the principle that justice needs to be justice for all, Ukraine should facilitate investigation of possible crimes by Ukrainians against Russians—not just crimes by Russians against Ukrainians. Professor Wexler contends that while U.S. and allied support for Ukraine must remain steadfast, encouraging Ukraine to make sure that all potential war crimes are investigated strengthens rather than weakens its moral authority.

Dean Falvy, a lecturer at the University of Washington School of Law in Seattle, describes the parallels between Russia’s invasion of Ukraine and Hitler’s invasion of Poland. Mr. Falvy argues that even if Russia can wrest more territory from Ukraine in the short term, it is difficult to foresee an end to the war it has started.
