Anyone with half a brain, that includes Putin, knows a counter offensive will come, so it’s hardly a secret. The particulars are what everyone can only guess at. But this much you know, it won’t be using WWI trench warfare human wave tactics. The Ukrainians are getting weapons and training from western nations that use highly mobile, combined arms, tactics. It is highly unlikely that the Ukrainian counter offensive will play into any Russian meat grinder theory. The Ukrainians could goon it up, but the allies training them will train them to use those weapons with speed and effect.
We’ll see if anyone “wins”. I could care less. Ukraine is a European problem and their main concern is climate change like it is here. The whole fxcking country here is a mess. Ukraine is irrelevant as is the rest of the world until we fix this shxthole.
