I've long felt it's time we put out some red lines of our own and make our intentions clear, as in, get out of Ukraine or we are going to make you, NATO or not. Make it clear we won't engage in Russia (so as not to violate Russian Nuclear doctrine), but to pretty much deliver an ultimatum that it's time for Russia to go the fuck home. A clear message, broadcast across the world, "you have 48 hours to begin to leave, and 2 weeks to be fully gone, or we will clear the air space and ground targets." Unlike Russia's red lines, our need to be concrete. Make it abundantly clear that it's over, if that makes us the bad guys in the eyes of the Russian population, so be it (here's hint, that's how this ends anyway, so who fucking cares?).
I don't give a rats ass about ever doing business with these idiots, so to me, who cares about that concern? Leave them isolated, strangled with economic sanctions, and humiliated. Fuck em. Make conditions so fucking bad in Russia that if they want to rejoin the modern the world, they are going to have to make massive changes.
