The Russian offensive in eastern Ukraine appears to be losing momentum. Their massive losses require reorganization, and decimated units are now merged on the fly to remain capable of combat. This situation is a commander's nightmare, and it is a desperate tactic.
The Russian invaders of Ukraine are out of reserves and out of supplies. They are mostly out of modern weapons and are now reduced to fighting with out of date Soviet era equipment, while Ukraine is getting significant help with more recent weapons systems being sent from abroad. The Russian troops are out of their depth, out of their wits, out of breath, out of options, and out of hope to turn this in their favor. They are running out of gas, both figuratively and literally.
Putin, meanwhile, appears to be not only out of ideas, but literally out of his mind. He is refusing to face reality, and it might not be a facade any longer. If he keeps sending his troops to slaughter against the unrelenting and highly motivated Ukrainian defence, he might soon be out of an army.
It is a horrible thing to say, but if Russia depletes its army on the battlefield to the point where it no longer is a force to be reckoned with, it might be for the best. Russia must be forced to stop its expansive aggression, and if they don't have an army to send, they can't invade their neighbors and meddle in conflicts abroad.
There will come a day when Russia is finally out of Ukraine, and it just might come sooner than we expect.
