President Biden is considering supplying Ukraine with cluster munitions, despite the weapons being banned by many US allies. Ukraine is running low on ammunition and is seeking cluster munitions, which are known to cause grievous injuries to civilians. The decision to provide Ukraine with these weapons would separate President Biden from his closest allies who have signed an international treaty banning the use, stockpiling, or transfer of cluster munitions. Mr. Biden's top aides, including Secretary of State Antony J. Blinken, recommended the move, citing the urgent need for ammunition in Ukraine. The State Department, however, had concerns about the humanitarian impact and the potential for the US to be out of step with its allies. Despite these concerns, it appears that Mr. Biden's aides believe there is little choice but to provide the cluster munitions to Ukraine. The decision comes as Ukraine faces a dire ammunition shortage and believes the munitions are necessary to counter Russian forces. The Biden administration is expected to announce the decision on Friday.
