For more than four years, Russia has wagered that it can outlast Ukraine. The Kremlin has more troops, more resources, and a greater tolerance for casualties, betting that Kyiv — and its Western allies — will eventually lose the will to keep fighting.

Ukraine is carrying out increasingly sophisticated strikes deep inside Russian territory, forcing Moscow to defend military bases, energy infrastructure, and even symbolic strongholds like Crimea. At the same time, NATO support has strengthened, Europe is expanding its defense cooperation with Kyiv, and President Donald Trump has struck a noticeably warmer tone toward Ukraine than he did just months ago.
