I don't take you for anything, I'm just saying that viewing this conflict in isolation, as if this conflict is about a land grab (because Russia needs more land

) while admittedly is very beneficial for propaganda, couldn't be more erroneous.
So, they don't want natural resources, one of the biggest deposits of iron ore and a decent amount of uranium, to name a few. Russia also doesn't want easy access to the Black Sea and the largest power plant in Europe, not to mention the second largest Black Sea port in Odessa. Nobody cares about petty things like that.
Expanding military alliances that attacks other countries without UN approval,
You know damn well that UN votes are a joke since permanent members can veto any UN resolution and guess who is one of the 5 permanent members

The root cause seems to be the brainwashed thinking that status quo should be changed and NATO should spread to Ukraine, Georgia, Armenia, Belarus, Kazakhstan, Taiwan etc...
Why do you mix together countries with different politics and ambitions? For instance Belarus doesn't want to be a NATO member, contrary to Georgia and Armenia, but they aren't being asked by NATO to join. It's not NATO that is coming to them, but they're trying to get into NATO. Why is that? What are they so afraid? Maybe they don't want to become a part of the Soviet Union again?
Nah that is clearly not about natural resources, Russia already had easy access to the Black Sea, and has plethora of electrical power generation.
UN is the best thing we could come up with. If we destroy that, we're back to the strongest doing whatever he wants, and with China set to bypass US is that really what you want? Also, I'll gladly listen to your alternatives to UN
Because we've already been through this, the precedent was set and continues to be up kept. It doesn't matter how much Cuba wants to be in military alliance with Russia, or how much beneficial Russia/China can make it for Cuban population, they can make Cuba the most prosperous place on earth, but non of this matters because US just won't allow it. And it's for the better, it's called spheres of influence and that's what kept our species from removing ourselves off this planet. But now one power decided to break that delicate balance, and change the status quo, with expected results from other powers.
