These aren''t exactly wins though. Mariupol is little more than a pile of rubble and the concept of a land bridge is barely relevant at this point given how depleted the Russians are in troops, morale, and weapons.
I disagree. They are wins because they allow them to leave small garrisons and redeploy the majority of their forces elsewhere. And that is relevant for the war. However depleted the Russians are, they are still advancing in the east.
Also the Russians, as clearly evidenced, do not give a single feck if the cities they take over are turned to rubble in the process. A city that is turned to rubble is also less likely to be a source of insurrection or trouble. It's not like the have plans to do anything with the cities for now. So if something is barely relevant at this moment, it's probably that imo.
They are holding Kherson because the Ukrainians aren't contesting them there. Once there is a full on battle, the Russians will be forced to retreat just as they did from the north and Kharkiv.
Yes on the first part but there won't be a full on battle for Kherson any time soon, because the main bulk of the Ukrainian forces is in the north and east. They don't seem to have enough troops, artillery and air support to redeploy to the south while maintaining those other fronts. Whereas having seen heatmaps of Russian mobile phone activity in Ukraine, the Russians still have considerable forces around Kherson. Majority of invading force from Crimea seems to be between Kherson and Zaporizhzhia
I also think the Russians have given up on Kharkiv now. Yes they are being made to retreat, as opposed to voluntarily retreating, but whether the Russian retreat from Kharkiv will be slower or faster than the retreat of Ukrainians from the Donbas is anyone's guess. I'm not sure the UA advancing force on Karkhiv will manage to reinforce Donbas defences on time, or if the Russian advance in Luhansk will reinforce the retreating forces from Kharkiv. There doesn't seem to be a prospect of encircling Russians in Izyum any time soon though.
As mentioned earlier, they are losing the battle of morale, troop readiness, weapons etc. Their only strategy that has worked so far has been to pulverize cities with long distance weapons (artillery and bombs). That only works if the other side doesn't have a response. Now that the Ukrainians are gaining howitzers loads of other sophisticated NATO grade weapons, they will probably start going on the offensive, which will start pushing the Russians back in many of the territories they hold.
They are losing many battles, but if their new objective to the war is to take Donbas secure the land bridge to Crimea and call it a day, then so far they are doing well. Worth noting, taking cities is generally very difficult. And it's especially difficult if you try to not pulverise them in the process, which is something the Russians don't give a feck about but I assume the Ukrainians will want to avoid doing it to their own cities. Kherson, Melitopol, Mariupol (and previously Luhansk and Donetsk) have all flipped. It will be very, very difficult for the Ukrainains to flip those back. Yes, they have managed to repel attacks at Mykolaiv, Kharkiv and Kyiv, but have not flipped a single city back. It's beyond their means at the moment. And whether they'll get enough weapons and tech to do that before the Russians secure the Donbas and entrench and fortify themselves, it's anyone's guess.
