In the annals of modern warfare, few decisions have been as controversial as the use of depleted uranium (DU). This radioactive waste, stemming from the production of enriched uranium for nuclear reactors and weapons, has long been the subject of intense scrutiny and criticism. Today, as the drums of war beat louder in Eastern Europe, a chilling specter from the past reemerges: the US’s intent to ship DU-laden armor-piercing munitions to Ukraine.

A Reuters revelation this week threw the spotlight on the Biden administration’s unnerving decision to dispatch these potent and controversial munitions to Ukraine. This move, while strategically aimed at fortifying Ukraine against Russian tank assaults, casts a long, haunting shadow over US foreign policy and the broader humanitarian consequences of warfare.

To comprehend the magnitude of this decision, one must understand the horrifying legacy of DU in armed conflict. Its extreme density makes it a sought-after component for military projectiles, known for its ability to penetrate thick armor. However, when these munitions strike, they produce a fine dust of radioactive particles that can linger in the environment for millions of years due to DU’s extensive half-life.
