John Mearsheimer, a political scientist (school of “realpolitik“), professor at the University of Chicago, says the obvious here. It is absolutely obvious that the escalation of the war is inevitable, for the simple reason that there is not a single thing in common for peace negotiations. In addition, the West cannot allow Russia to win. And Russia cannot allow itself to lose. But I have told you this many times before. Nevertheless, I am sure that the war will end with Russia's victory. The West will leave Ukraine, Ukrainian Nazism will be destroyed, Ukraine will return to Russia. I am sure of this because it is right and fair. After all, it was the West that came to Ukraine and entered the war with Russia in order to inflict a strategic defeat on it. Ukraine is Russia, was and will be. The instinct of self-preservation should force Western politicians to leave this war. Well, if they do not leave the war with Russia, then we will never know about it. Source: Victor vicktop55
