Soldiers don't do well in that infamous Ukraine mud, so Vlad better hurry.
What is really horrible is that NATO sanctions could actually increase global warming from utility emissions. If they suspend the Nord Stream pipelines, which is probably the form of sanction that would hit Vlad the hardest, then northern Europe will scramble for quick and dirty substitutes to NG. I mean, sure, Euros could mobilize a crash program of windmill farm construction, heat pump installs, and build next generation nuke plants, but none of that can happen fast enough, and I see that as hard to sell. Germany doesn't show any interest in new nuke plants. UK likes NG as a bridge fuel, and has lots of drafty old houses that converted and whose owners find heat pumps will cost twice the pounds per btu. It will be very hard to afford shutoff of Nord Stream.
