The Flawed Moral Logic of Sending Cluster Munitions to Ukraine

In the brutal logic of warfare, cluster munitions may appear to make solid sense for Ukraine’s slow-moving counteroffensive against well-dug-in Russian troops. Delivered by artillery, a 155-millimeter shell packed with 72 armor-piercing, soldier-killing bomblets can strike from 20 miles away and scatter them over a vast area.

On Friday, the Biden administration announced it would start delivering these weapons to Ukraine, over objections from, among others, human rights organizations and key allies. President Biden said the United States would supply cluster munitions from its large stockpile until suppliers could catch up with Ukraine’s shortage of conventional artillery shells, a key weapon in the static warfare in eastern and southern Ukraine.
