U.S. Cluster Munition Coalition Letter to President Biden

The Honorable Joseph R. Biden, Jr. June 14, 2023 President of the United States

The White House

1600 Pennsylvania Ave, NW

Washington, DC 20500

Dear Mr. President,

We, the undersigned organizations, write with grave concerns over the potential transfer of United States cluster munitions to Ukraine. We sincerely appreciate your Administration’s firm stance in not transferring any U.S. cluster munitions to Ukraine to date. Despite recent calls from members of Congress and Ukrainian leaders for the United States to transfer cluster munitions to Ukraine, we strongly urge you to remain steadfast.

The U.S. Cluster Munition Coalition condemns in the strongest possible terms the use, production, transfer, or stockpiling of cluster munitions by any party. Cluster munitions are among the most harmful weapons to civilians, as they are designed to disperse indiscriminately across a wide area and often fail to explode on initial use, littering communities with unstable unexploded ordnance and causing devastating harm to civilians, and especially children, years after a conflict ends.

Cluster munitions have been used repeatedly by the Russian military since its full-scale invasion in February of 2022, with devastating impacts on civilians and civilian objects, including homes, hospitals, and schools, according to Human Rights Watch. The Ukrainian military has also used cluster munitions on multiple occasions. On April 8, 2022, a cluster munitions attack by Russia killed at least 58 civilians and injured over 100 others in the city of Kramatorsk—this is just one of the hundreds of documented, reported, or credibly alleged, cluster munition attacks in Ukraine since the 2022 invasion. The United States must not be complicit in the use of these indiscriminate weapons.

Any claims of potential tactical benefits of the transfer and subsequent use of cluster munitions by Ukraine in the defense of its territory, dismisses both the substantial danger that cluster munitions pose to civilians, and the international consensus on their prohibition.

Were the United States to transfer these prohibited weapons, it would run counter to the global consensus, embodied in the 123 countries who are signatories or states parties to the Convention on Cluster Munitions, which bans the use, production, transfer, and stockpiling of these weapons. While neither the Russian Federation, Ukraine nor the United States are party to the Convention, 23 NATO members are among the states parties. Beyond making the United States a global outlier, acting in contradiction to partner nations’ and NATO allies’ express ban on the transfer and use of these weapons could hurt the U.S.’ ability to forge and maintain coalitions that have been so crucial to supporting Ukraine. It would also harm efforts to promote other arms control agreements.

Although the United States is regrettably not party to the Convention, a long-standing congressional mandate prohibits the transfer of any cluster munitions with a failure rate greater than 1%, which effectively forbids the transfer of any existing U.S. stockpiled cluster munitions. Additionally, twice in the past year, members of Congress have written your Administration calling for the United States to “be leading the global effort to rid the world of these weapons, not continuing to stockpile them” and urged you to “promptly order a review of U.S. policy on cluster munitions with the goal of halting their use, production, export, and stockpiling and putting the United States on a path to join the Convention on Cluster Munitions.” We urge your Administration to continue to heed this congressional mandate and intent.

Cluster munitions are indiscriminate weapons that disproportionately harm civilians, both at the time of use and for years after a conflict has ended. We greatly appreciate your committed stance against transferring these weapons while supporting the Ukrainian people – and we urge you remain resolute in resisting recent calls.
