Ukraine was making up for shortages of missiles with home-produced weaponry and air defense systems, “but it is not enough,” Zelensky told Washington Post US military aid for Ukraine had been stalled in the Republican-controlled US House of Representatives KYIV: President Volodymyr Zelensky said in an interview published on Friday that if Ukraine does not get promised US military aid blocked by disputes in Congress, its forces will have to retreat “in small steps.” “If there is no US support, it means that we have no air defense, no Patriot missiles, no jammers for electronic warfare, no 155-milimeter artillery rounds,” Zelensky told the Washington Post. “It means we will go back, retreat, step by step, in small steps,” he said. “We are trying to find some way not to retreat.” Shortages of munitions, he said, meant “you have to do with less. How? Of course, to go back. Make the front line shorter. If it breaks, the Russians could go to the big cities.” Democratic President Joe Biden has urged the Republican-controlled US House of Representatives to endorse the military and financial aid package, but House Speaker Mike Johnson has held up the matter for months, citing domestic priorities. Zelensky told Johnson in a telephone conversation on Thursday that approval of the package was vital. Russian forces captured the eastern town of Avdiivka last month and have made small gains since, but the front lines have changed little in months. In his interview, the Ukrainian president said Ukraine was making up for shortages of missiles with home-produced weaponry and air defense systems, “but it is not enough.” More than two years into the war, Russia has intensified attacks on energy and other infrastructure in recent weeks. Ukrainian troops have been unable to advance, and Zelensky said Kyiv intended to pursue attacks on targets in Russia, including oil refineries. He said Washington’s reaction to the wave of Ukrainian attacks was “not positive,” but Kyiv was using its own drones. “We used our drones. Nobody can say to us you can’t,” he told the newspaper. If there is no air defense to protect our energy system and Russians attack it, my question is: Why can’t we answer them?” he said. “Their society has to learn to live without petrol, without diesel, without electricity. When Russia will stop these steps, we will stop.”
