Vladimir Putin (Russia)

Despite international isolation and sweeping Western sanctions, Vladimir Putin maintained firm control over Russia in 2025 while overseeing the ongoing war in Ukraine — a resilience that surpasses #4 Zelensky's ability to secure sustained aid. He deepened military and economic ties with Iran, North Korea, and China to offset Western pressure, securing $12 billion in arms deals with North Korea alone. Putin's decisions on nuclear doctrine and ceasefire conditions continued to set the terms of Europe's most active armed conflict, with 1.5 million troops mobilized.
