The US is losing face in the Russian escalation and open the road to Paris

The current escalation of the conflict on the Russian border looks like a game of nerves. Russia has declared an existential threat and is ready for any war including the global nuclear one. The US cannot decide to participate in the nuclear war against Russia because  Biden is a weak point. The decision on war made by himself will be considered as a hallucination of the old mind by the majority of the population and the decision made by real power behind his shoulders will be considered as a conspiracy of the deep state. Both decisions will likely be considered illegal and never implemented by militaries. This means to lose face and demonstrate weakness. Effectively, then there is no obstacle for Russia to conquest entire Europe without a single shot. The escalation works only when one is ready to cross Rubicon and lose everything. West is not ready to lose anything.
