U.S. authorities are working to strengthen Ukraine's air defense system (Air Defense), White House press secretary Karine Jean-Pierre said at a briefing on Wednesday, without specifying whether Washington considers the transfer of Patriot missile defense (ABM) systems to Kyiv advisable.

According to her, they are in close interaction with the Ukrainians about their security needs.

Jean-Pierre was asked to comment on information that Berlin and Warsaw had reached an agreement on the deployment of Patriot systems in Poland. In response, she noted that it was up to Polish and German authorities to comment on the agreement, but added that in general the U.S. welcomes the efforts of allies to strengthen NATO's collective defense.
