Sorry, I do not see that escalation.
Putin is an evil devil, that is certain, but take on the whole of NATO, no way! Foolish to believe that would ever happen.
I do believe Trump will be backed into a corner to support Ukraine in an unrestricted way, dumping 100s of billions in military aid to Ukraine, or force Ukraine and Russia to end the war. I am of the optimistic opinion he will choose the latter. He will force both to end it. He will not make it happen in 24 hours like he said he would, and it will not be over before he takes office, another promise, but I do believe he will bring it to an end. I figure 6-12 months to manifest a truce between the two nations.
