The reason why the Russia-Ukraine war broke out is that Russia wants to integrate Russia, Ukraine, and Belarus to recreate a Greater Russia. This goal has failed in the first week of the war. The current objective is to seize more Ukrainian territory and establish a New Russia.
Anyway, it's impossible for Russia to lose. Since the beginning of the war, when Russia had over one million troops, it has now expanded to 2.5 million troops. The longer the war goes on, the stronger their forces become.
On the Ukrainian side, Trump, who leads the country, is Putin's younger brother and has unlimited admiration for Russia. Now, the United States has cut off its aid to Ukraine. Without American aid, can France or Britain win the war? France produces only 36,000 shells per year, while North Korea alone produces 3 million shells. How can you fight with just one shell for every hundred they fire?
In essence, this is a cost-benefit issue. It could be the entire Ukraine, half of Ukraine, or just the four eastern states, or even a ceasefire at the current line of engagement.
Russia has paid such a high price, using up the weapons and ammunition reserves prepared by the Soviet Union for World War III. Just the four eastern states are not enough to satisfy Russia; it also wants Odesa, Mykolaiv, and Sumy.
