Ukrainian President Volodymyr Zelenskyy called on world leaders during a speech at the U.N. General Assembly on Wednesday to continue limiting Russia's financial resources and to hinder its ability to sustain the war. Zelenskyy emphasized that allowing Russia to generate more revenue through trade would prolong the conflict. "When someone gives Russia more money through trade, they give this war more time," he said, speaking in English. He added that Ukraine is actively working to "burn Russia's revenues" by restricting trade with the country. Zelenskyy also criticized Russian President Vladimir Putin, suggesting that something prevents him from ending the war. "Can you even imagine him without war?" he asked. Zelenskyy referred to Putin as "Patient Zero," the original source of the conflict, and argued that he must be stopped to prevent the war from spreading further. Russia is set to address the U.N. General Assembly on Saturday, but Putin himself has not attended in recent years. Instead, Russian Foreign Minister Sergey Lavrov spoke on Wednesday, stating that Russia is open to negotiating a lasting peace but opposes a temporary "pause" in the war. Lavrov warned that such a pause would only give Ukraine and its allies more time to acquire weapons. The war, which began more than 4½ years ago when Russia invaded Ukraine, has resulted in heavy casualties on both sides. Western analysts estimate that over 500,000 Russian troops have been killed, and Ukraine has recorded more than 500,000 military casualties, including up to 140,000 deaths. However, both countries have not officially disclosed their own casualty numbers. The conflict has had far-reaching global effects, disrupting fuel, fertilizer, and grain shipments and deepening the divide between Russia and the West. Front-line positions in eastern and southern Ukraine have remained largely unchanged since last year, but both sides have increased the use of long-range drones and missiles. The war has shifted to a more strategic phase, with both nations focusing on sustained attacks and defense efforts rather than large-scale territorial gains. As the conflict continues, international pressure remains on Russia to end the war, while Ukraine seeks continued support from its allies to maintain its defense capabilities.
