Russia has suffered an estimated 1.2 million casualties in Ukraine, a scale of losses not seen for a major military power since World War II, according to a new report by the Center for Strategic and International Studies.
Despite the heavy toll, Russia has expanded its control of Ukrainian territory by only about 12 percent since the 2022 invasion, the report finds.
The findings challenge claims that a Russian victory is inevitable. President Donald Trump said last month that Russia holds the advantage due to its size and strength.

Russia’s losses far exceed those from all its postwar conflicts combined.
Analysts warn that Moscow’s recruitment cannot keep pace with deaths and injuries, while the war is also weighing heavily on Russia’s economy and long-term growth prospects.
