You are buying Blinken’s denial, where he is trying to talk hair when the head is at stake.
Russia is obviously not going to nuke Europe because her defense doctrine is based on MAD, Europe is not a side to, not counting the American strategic infrastructure there. Poland is not capable to threaten Russia on her own.
It is the essence of Putin’s ultimatum. He is essentially threatening CONUS, but Blinken is playing idiot and trying to downplay it into the Ukrainian issue.
It was, is, and always will be about the strategic balance between the US and Russia. Everything else is irrelevant and a distraction.
B.S.
The only real “balance” issue is NOT U.S. vs Russia, it is Russia vs Western Europe; which the U.S. via NATO is pledged to help protect. Putin wants the U.S. to pretend its just about MAD and Russia vs U.S. while it maneuvers “conventional” forces to threaten/pressure Western Europe. That’s what the build up next to Ukraine is about. Poland and others are having none of it; they know Putin’s game.
