Here is the deal...
In every war, opponents always tried to exploit each other's weaknesses, flaws, ignorance, and incompetence. Great multi-stars military leaders became 'great' because they excelled at recognizing when/where/how to exploit. The corollary is that leaders, political and military, were derided because they failed to address their own weaknesses, flaws, ignorance, and incompetence.
The video above gives the latest updates on how Russia is faring in Ukraine. People can turn against Ukraine and points out how Ukraine is corrupt, militarily small, inept conscripts, and so on and on. None of those accusations are false. But that is precisely the point. Russia, after two yrs, failed to exploit Ukraine's weaknesses, flaws, ignorance, and incompetence. But even if Russia tried to exploit, Russia failed, so what does that say about Russia's military leadership? Not good.
Two things can be true at once without colliding against each other where one negates the other. That Ukraine is corrupt inside a list of serious problems. That Russia despite their size revealed to be an utter failure as a military power. Both are true. Ukraine failed to exploit Russia's failures on the battlefields, but at least Ukraine has the excuse that they are smaller than Russia, and it is a credible excuse. Historically, the larger usually preyed on the smaller, and usually the larger won. International aid to Ukraine upsets this norm. Did Russia anticipated this? No. Then why not? Remember, the communist bloc aided communist insurgencies around the world during the Cold War yrs. That qualified as 'international aid'. The most notable ones were Korea and Viet Nam. Did that failure to anticipate made Russia overconfident that whatever military forces arrayed against Ukraine would win? Absolutely. Overconfidence is a great flaw and everyone was guilty of that one time or another.
Ultimately, Russia can still win in Ukraine, but at great cost. Politically speaking, Russia will be isolated and reviled. Militarily speaking, the Russian military will be relegated to Third World status. That does not mean the EU countries will not fear the Russian military. A rusty knife can still do serious harm. But how ever which way the Ukraine situation will turn out, everyone will know how to restrain the Russian military, and embarrassingly so.
