U.S. Ambassador to NATO Julianne Smith said this in an interview with POLITICO, according to an Ukrinform correspondent.
"I think we're also very clear-eyed that this particular counteroffensive may not determine the end of this war," Smith said.
At the same time, she noted that she wishes success to Ukrainian efforts on the battlefield.
"We want the Ukrainians to continue to undertake efforts that will shift Putin's strategic calculus, and help him understand that he is failing and that he will not achieve his strategic objectives, and I think a successful counteroffensive could be helpful in that regard," the ambassador said.
As reported, Moscow is launching fake news about the counteroffensive and losses in Ukraine's Armed Forces. Russian propaganda media and social media are spreading a lot of false information in a bid to demoralize Ukrainians.
