Ukraine can not lose. All those people who say so many Ukraine patriots have died are puppets of Putin-Hitler. Now—it is Ruzzians who have lost millions of men. Ruzzia is about to go into rebellion against the horrible loss of her young men. The war is reducing Ruzzia into a weak failed nation state—weaker than Iran. They will be withdrawing soon back to their worthless tyranny. Putin will die! His Bridge to Russia blown up! No more war and a new peace will come to Europe. Victory by New Years day! Send more F-16s Abrams Tanks, and money.
I hope that you are correct. As to current developments, Ukraine is degrading the Russian grip on Crimea, while a fierce, hurricane like storm damaged Russian defensive trenches and emplacements on the beaches there. Meanwhile, despite the risks, there are rising protests by Russian women against the conscription of their men, while the Russian civilian economy is under severe stress.
