Re: I like 7Zip.
Yup. And Whilst I wouldn't like to bet against Putin having delusions of modern Tsardom, AFAIK there's a significant amount of oil and gas was spotted a few years ago in Donbas, in the sea of Azov, and around Crimea. <sarcasm> I'm sure Putin was desperate to liberate the opressed hydrocarbons from their opressors, so that's all right, then, eh? </sarcasm>
To add my two penn'orth to the argument going on in this comments section; I grew up during the Cold War, and nuclear warning sirens being tested now and then was a part of my childhood. Whilst I didn't undertand what was going on to the extent that I do today, I didn't hate the Russians - I hated the Russian leadership and was highly skeptical about the American leadership, both for essentially making so many millions or billions live in fear for so long.
Putin is emhatically NOT a master of propaganda. He and his propagandists are making stupid errors that no one good at propaganda would make. But because he is a dictator, he does have full control over Russia's media, so the only news most Russians encounter is what Putin wants them to hear, and like it or not, that's going to at least temporarily convince some who are subjected to it on a daily basis that there must be at least a core of truth to it.
However - the Russian regimes self-contradictory lies are catching up with the. More and more Russians are spotting the contradictions and questioning the official line as to what is happening. More and more are becoming aware that Russian asualties have been heavy, that loved ones aren't going to be coming home, and that raw conscripts were pushed into combat inadequately equipped and supplied as cannon fodder. Unsurprisingly, more and more are getting angry that young Russian lives are getting carelessly thrown away in this manner. In short, word is spreading in Russia that Putin's version of events is far from truthful, to the extent that anger is starting to overcome fear.
As for whomever claimed that Russia will eventually overrun Ukraine; I have reason to doubt that you understand the situation there or military matters in general very well.
In brief, if the Russian armed forces were what most people (myself included!) thought they were and were supposed to be ie a well equipped, well-trained and well-lead modern army then I'm pretty sure that Ukraine would have fallen completely under Russian control inside a week or two. But there is just so much evidence of the complete and utter incompetence of the current Russian military at all levels, and of corruption misappropriating funds that were supposed to maintain and update equipment mysteriously finding its way into individuals bank accounts, that no, there is no way Russia could win this war even if it could afford it for much longer, which I rather doubt.
Ask yourself - why did the Russians employ Wagner Group? What competent modern superpower would NEED to? And please don't trot out the "The Russians haven't put their best into the front line yet" because they did, right at the start - and they were heavily defeated by the Ukrainians to the point of being no longer capable of combat operations, so they were pulled out of the fighting. Sure the Russians do hve a Professional core amidst the sea of conscripts, as well as those who can operate artillery and rocket systems, but it's armed and competent boots on the ground in the frontline that take and hold territory - and that's something in very short supply in Russia, currently.
The thing about those with a thuggish criminal mentality is that they think that ll it takes to get their way is to send some heavily armed lads around to put the frightners on the intended victims (or kill them). Which , to my surprise, appears to be what has happened to the Russian military. Instead of being a professional modern fighting force, it has devolved into a criminal gang commanding a core of professional troops amidst a sea of corrupt thugs commanding barely trained conscripts. It's not an army - it's a Mafia gang writ large.
