White House spokesman John Kirby said this in an interview with Voice of America, according to Ukrinform.
"We know that in the spring when the weather improves, and it's already starting to improve, that we can expect the Russians to want to go on the offensive in some areas," Kirby said.
He said he did not know exactly where the Russians would want to advance. However, according to him, the United States wants to provide Ukraine with better opportunities for defense. If the Ukrainians choose offensive operations of their own, they can also take advantage of these capabilities, Kirby said.
"We have evolved the capabilities that we are providing Ukraine," he added.
Kirby also listed the current needs of the Ukrainian Armed Forces, among them armored vehicles, artillery, air defense, and logistics.
