Yes Russia is quite capable of destroying the Ukrainian military through the use of superior and overwhelming firepower, but it hasn't done so and that's the problem. We are four an half months into this war and the Russians haven't decimated their enemy. At the start they had the superior and overwhelming firepower to destroy the Ukrainian military, but they wasted it, using it piecemeal and the lost a lot of it and more importantly, experienced troops, in the process. They have made some gains, but slowly, at great cost and they still haven't be able to knock Ukraine out of the fight. Most of the time the Ukrainians know what they are going to do before they do it themselves because the Ukrainians read the same strategy and operations manuals and used the same doctrine. Big difference now is that the Ukrainians have evolved strategically and tactically, adapted and overcame, but against the Russians they always lack quantity which has a quality of its own.I don't think this was intentional. I think Russia genuinely tried to cut off and encircle for destruction Ukrainian forces defending Severodonets-Lisichansk first, and Zolotoe-Gorksoe afterwards. Both failed to do what they were aiming for. Pro-Russian sources were reporting, likely from internal sources, that Ukrainian POWs are imminent. Yet they never materialized. I think this was another failure. Russia can advance but not fast enough to do this. I think Russia can demolish Ukrainian forces, but primarily through superior and overwhelming firepower.
I totally disagree with you trying to frame the war against Ukraine as a "Jihad and the defence of Islam" because it is most definitely not and is the farthest thing from it. Religion does enter into it on the sidelines, but it's a power battle between to Orthodox Christian Churches with the Russian Orthodox Church reacting bitterly to the loss of its hegemony and control over the Ukrainian Orthodox Church that it wasn't supposed to have anyway. The Russian Patriarchs are quite bitter and twisted about it because for them it's a huge loss of power, wealth, and prestige.For those wondering about the "aims of the special operation" - short and simple - "Jihad and the defence of Islam". The Kadyrovites are ignorant people who do not know what Islam means. These people call Jihad their job as mercenaries. Jihad is above all a moral self-improvement. These hired killers are betraying Islam. Chechnya is totally subsidized by Russia.
If your Chechens decide that they want to visit Berlin without an invite, best that they make sure that their affairs are all in order because once they set foot in NATO territory uninvited they won't be returning home healthy, if at all. The Poles will take a very dim view of them trying to cross their territory and they won't be very nice about it. They have no reason to like Russia or any of its vassals fighting for it, and the Poles have long memories. The Germans are lucky that the Poles have a stronger dislike of the Russians than they do of the Germans. Considering what the Russians and their Chechen vassals are doing in Ukraine at the moment, I wouldn't give your Chechen mates much chance in Poland because from what I understand the Poles are quite angry about it.
