Russia learns from failure to take Kyiv as new offensive begins, U.S. says

Russian forces are learning from their frustrated assault on Kyiv as they shift to the Donbas region, in eastern Ukraine, and are trying to avoid a repeat of earlier mistakes, the Pentagon and defense strategists say.

Moscow has been amassing troops and supplies for weeks in preparation for a renewed ground offensive in eastern Ukraine, after Kremlin forces failed to capture the capital during the first phase of the war. Nearly two months later, Moscow is taking heed of at least some of the errors that derailed its northern campaign.
