With high casualty figures and the slow pace of Russia’s territorial gains, President Vladimir V. Putin could face years more of a grinding war of attrition in Ukraine.

Nearly 1 million Russian soldiers have been killed or injured in the country’s full-scale invasion of Ukraine, according to a new study, a grisly measure of the human cost of Russian President’s Vladimir Putin’s unprovoked three-year assault on its neighbor.

A new Center for Strategic and International Studies (CSIS) report, “Russia’s Battlefield Woes in Ukraine,” challenges the narrative of Russian dominance, suggesting Russia is performing poorly. -It projects Russian military casualties (killed and wounded) will reach nearly one million by summer 2025.

It would be the third such attack. The claim comes two days after one of Ukraine’s most ambitious operations of the war, deep inside Russia.

Ukraine's SBU security service said it had hit the road and rail bridge linking Russia and the Crimean peninsula below the water level with explosives.
