Stalemate is something even the best marketing firm couldn't sell at this point. imo Its not really about land capture, heck, even Israel isn't really capturing land.
No ammo + no men eventually + fabs working west
=
Earth's biggest parking lot (Ukraine)
So, the Ukraine needs a very steady stream of men to learn to sit there and take a fab to the head to prolong it, so as long as they get a steady stream of dummies in there it will take time.
Its all about reserves, capacity and production. $60 billion isn't going solve it and $600 billion isn't going to solve it or even $6 trillion. I do believe it could go on for some time, stalemate, no, moving fast, nope. Grind, yup. Its going to take a long time to flatten that place down to the dirt. Israel and Russia have figured it out... you just flatten everything. You just keep running the cycle over and over, move West, cycle over and over until it looks like you can park your car there, move west, cycle over and over. Its not really all that difficult at this stage.
Both Israel and Russia's goals are really to destroy men and return all those human structures back to the Earth. Russia at this point is simply running the greatest demolishing project the world has ever seen. Its not complex.
