Russia’s response is to not try to win this militarily, but economically.
Right now, they don’t need to win on the battlefield, they just need to not loose.
Keep up the pressure and attrition NATO weapons and ammo as fast as NATO can pump them into Ukraine while keeping its own combat losses, especially manpower, down as low as possible; while starving the Euros of energy and wait for the EU to collapse into internal chaos and infighting and/or stab Ukraine in the back to end the war before it ends their economies.
That is why Russia is taking its sweet time advancing, yet quick to withdraw and abandon equipment in favour of saving their troops’ lives whenever it looks like the Ukrainians might force them into a fair or even disadvantaged fight.
This is also why NATO had the Ukrainians make these crazy hailmarry offensives, to try to end the war before winter hits and the full economic damage is done. It’s also why all the crazies are coming out of the woodworks to suggest invading Russia itself. Someone is envious of Russia’s oil and gas fields again. That’s what the Ukraine gambit was all about from the start. Although it’s turned on it’s head where the Russians are absolutely crushing the economics war while massively underperforming on the battlefield while NATO is now desperate for an impossible lightning victory to stave off economic disaster.
People told me about six months ago that Russia is going to win by military force and this just demilitarization of Ukraine. Cauldrons and all that stuff... remember? But now when Russians military is running away it's suddenly about winning economically. Russia has lost 2/3 of it's export economy, so i'm not sure what they are winning, sure as hell aren't winning on battlefield, and if we look figures they are losing even worse economically. That's why Russiand and their shills are whining about sanctions.
"Of course Russia is a superpower. This war gonna last few weeks".
"They never wanted Kyiv. It was a feint".
"Snake Island? We'll Russia never needed it anyhow".
"They never wanted Odessa. it was a Feint".
"They never really wanted Kharkiv. It was a feint".
Fact is that Russians are right now hitting at Ukrainian civilian infra (again) because second/third third rate military cannot get any victories on battlefield, well, they took a hill yesterday.
