The world shuddered, expecting the consequences," Medvedev said. "Belligerent Europe was disappointed."Russia didnt care," he added.Reactions to Trumps latest frustration with Putin were mixed, as Rutte championed the move as "logical," though top European Union officials suggested the move lacked teeth this far into the war."On the one hand, it is very positive that President Trump is taking a strong stance on Russia. On the other hand, 50 days is a very long time if we see that they are killing innocent civilians, also every day," the EUs chief diplomat Kaja Kallas told reporters from Brussels when asked about the presidents announcement."It is clear that we all need to put more pressure on Russia so that they would also want peace," she added. "It is good that the Americans are making the steps, and I hope that they are also giving military aid like Europeans are giving."TRUMP REVEALS MELANIA'S KEY ROLE IN DEALING WITH PUTIN ON UKRAINE WARKyiv Mayor Vitali Klitschko also questioned the effectiveness of the move and told German news outlet ARD that "Im happy about the wave of support from the U.S.""But on the other hand, I do not understand why Kremlin leader Vladimir Putin is being given 50 days," he added, according to a translation by Ukrainian media outlets, Kyiv Independent."In 50 days, many more people could be killed in the capital and, throughout Ukraine, many more buildings could be damaged," he said. "Therefore, why such a delay?"Trump told reporters on Monday that he was frustrated by Putins lack of action when it came to stopping his war in Ukraine despite four separate occasions when the president thought a deal had been reached with the Kremlin chief."I speak to him a lot about getting this thing done, and I always hang up saying, Well, that was a nice phone call, and then missiles are launched into Kyiv or some other city, and I'd say 'strange,'" Trump said, recounting his conversations with Putin."And after that happens three or four times, you say, the talk doesn't mean anything."
