As Ukraine requests more weaponry amid its counteroffensive against Russia, the Biden administration is weighing whether to supply Kyiv with controversial cluster bombs. Senior U.S. administration and defense officials have contacted lawmakers to assess their comfort with sending the munitions, people familiar with the matter told The Washington Post. The Biden administration has concerns about the optics of the move and the potential for long-term harm to civilians, as the munitions can leave behind unexploded bomblets that remain deadly for decades.
