Ukrainian President Zelenskyy warned world leaders at the U.N. that we’re in “the most destructive arms race in human history,” urging action to stop Putin before Russia’s war spreads further in Europe. He said weak institutions have failed to halt wars from Ukraine to Gaza, and that “weapons decide who survives.” Zelenskyy thanked the U.S. and Europe for support, stressing that stopping Russia now is “cheaper than catastrophe later.” He also called for urgent global rules on AI weapons as drones reshape modern warfare.
