I agree that it is going to happen. For a few reasons:
Blinken is the weakest sec of state I can ever remember, I have never seen anyone project weakness the way he does.
Russia has entered a meat grinder situation, the losses they are taking is surprising, I keep waiting for Russia to just level Ukraine indiscriminately. It is coming pretty clear they dont have the resources to perform a long term ground battle.
Sanctions are going to take their toll on the Russian people, and at somepoint they are going to rise up. The fact 3000 protestors have been arrested already means their isnt the appetite for it in Russia and as conditions worsen the people will grow restless. The narrative will need to switch that this isnt about liberating Ukraine but an all out attack on Russia.
My biggest fear is that Putin will do a tactical nuclear strike on an Eastern European NATO country. How does the US/Euro respond?
In the same token, it seems the US is not taking the threat seriously, using Russia to help negotiate with Iran, meeting with Venezuela, buying Russian oil and keeping that part of the Russian economy open to SWIFT.
There is a lot more questions than there is answers.
