LONDON, Dec 22 (Reuters) - Russia said on Thursday that U.S. supplies of Patriot missile systems to Ukraine, announced during Ukrainian President Volodymyr Zelenskiy's visit to Washington, would not contribute to settling the conflict or prevent Russia from achieving its goals.Peskov said that there had been no calls for peace or signs of willingness to "listen to Russia's concerns" during Zelenskiy's visit on Wednesday, proving that the United States was fighting a proxy war with Russia "to the last Ukrainian".Before addressing a joint meeting of Congress, Zelenskiy held a meeting with U.S. President Joe Biden at the White House, during which Biden pledged to deliver one Patriot surface-to-air missile battery systems.Ukraine had previously requested Patriots, saying that they would help bolster its air defences as Russian missile strikes on critical infrastructure have become more regular.Ukrainian troops will learn how to use it in Germany, and it will be several months before they can deploy it on the battlefield."
