The flaw in your thinking is that if Russia/Putin has enough strength to do what you say, they certainly have enough strength to win the war... easily win the war.
Then why don't they win it? They are simply not of the mindset to destroy their Ukrainian 'relatives'. After all, the reason they entered Ukraine in the first place was to save their brothers and sisters in Donetsk and the Donbas.
The war isn't against Ukraine. It's against the everlasting encroachment of the US, Nato, and the Federal Reserve banking system.
No this is a war in which Ruzzia has tried to topple a democracy and then invaded Ukraines sovereign borders - and before that they had been financing terror in the donbas. There is no liberation of any kind.
The narrative about brotherhood and liberation is false. Putin's money created a proxy war / frozen conflict where there was nothing but people living peacefully. How does a dictator free you for anything other than becoming his slave? Putin cannot finish the war, he can simply cause as much destruction and innocent deaths as possible, that is what is left for him to avoid an internal coup (another?). The narrative about "goodwill" gestures is another sack of shit.
It is just impossible to believe any of those arguments by simply looking at the basic facts, this is just for Republicans that are trying to justify another Trump term.
Sure hey, I agree, he does not have enough strength to invade Poland and not even enough strength to win over Ukraine - but that is as long as the US, EU an Ukraine actually do something to stop him. Bullies that get their nose punched do not come back for more. You let them their way, they come back again and again.
I truly suspect that not all of what Putin and his cronies are doing is honorable. But it is far more honorable than Zelensky and HIS cronies. After all, the whole voting scheme in the Ukraine was manipulated by the US. You can tell by the millions of Ukrainians who fled to Russia for salvation from the Zelensky group.
Democracy is simply a more complex, group Dictatorship. In this case, it is being used by the US to attempt to bring Russia down through Ukraine. All of what Russia is doing is simply self-protection.
You are entirely missing what is going on... or you are a US/Nato/Ukraine propagandist. And the big thing you are trying to hide is your contradiction regarding the war. If Russia has enough strength to do the things that you accuse them of, they certainly have enough strength to win the war by force, easily... if their goal was to simply destroy Ukraine.
