Having foreign troops deployed along the contact line would make it very dangerous for Russia to begin a new war. They are afraid of supporting forces, bases, and international representatives. If we don’t have this presence, no words will stop Putin. And if we truly want to stop him, I am not sure that powerful countries can be mediators. If you are mediating, he doesn't feel guilt. This is a big problem. I'm not forcing anybody to pick sides. But the thing is, if we want to end the war, we have to tell Putin he is not right. I am not sure that dialogues built on compromise work. I think that President Trump, President Xi, Prime Minister Modi, and other big players in the world have to tell Putin he has to stop this war. They can't tell Ukraine “You have to stop the war”. We are defending. We are not aggressors. To stop what? All together, we must stop Putin. What does it mean to be a great leader? It means stopping the war through diplomacy. From an interview with CNN (2/3).
