He stated this in an interview with The Telegraph."Putin is a KGB agent. He never stopped being one. He doesn't understand the West. He pretends not to speak English, but he actually does, and we have caught him doing it more than once," Kellogg noted.According to him, the Russian dictator is a manipulator who can only be restrained by force, power, and determination.When asked by a journalist about the possibility of improving U.S.-Russia relations in the future, the special representative noted that this is possible only after Putin."It is possible only after Putin. Until Russia returns to the circle of civilized nations — it remains an outcast," he stressed.Kellogg also believes that the head of the Russian Federation is under the illusion of victory, but in reality, the situation is not in his favor."He (ed. - Putin) is being misled. Unfortunately, he believes he is winning this war, but that is not the case. So Trump is just giving him the space and time to come to the negotiating table. But we still hold all the cards," he added.On September 18, U.S. President Donald Trump said he had considered resolving the war in Ukraine the easiest issue, but Russian leader Vladimir Putin “let him down”.
