Russia has endured over 700,000 casualties since launching its full-scale invasion of Ukraine in 2022—more than in all of Moscow’s conflicts since World War II combined, U.S. Defense Secretary Lloyd Austin said on Jan.

Ahead of President-elect Donald Trump’s return to office, Ukraine’s future course is shrouded in uncertainty as it loses ground to Russia’s far larger military.

Even as Russia seems to have the upper hand in its invasion of Ukraine, the Kremlin faces a growing number of challenges that will complicate any effort to lock in its gains, the outgoing Pentagon chief said.
