In this war, the weak points of both warring parties are similar. Russia's weak point is that everything depends on Putin. When Putin took Crimea, he said that if he left for a day, everything would stop.
However, Putin's opponents have exactly the same weakness. Hyper-centralization of control in the center in Washington. As soon as America truly surrenders(we certainly won't take seriously this funny performance that Trump is currently putting on), all the American puppets around the world (UK, EU etc) will immediately run away.
