Facing a numerically superior foe, Ukraine is under pressure to replenish its ranks on the battlefield where, after three years of war, recruitment is already a challenge.

Ukraine’s air force said that Russia launched 728 exploding drones and decoys, a barrage that set a single-night record and underscored Ukraine’s need for weapons. Trump, who just last week paused arms shipments to Ukraine, said on Monday that the U.S. would resume them because the country was “getting hit very hard.”
