You are looking very much like a Russian apologist, and we all know what that means. You probably thought you were hiding but this is an educated board, and as such we can see through it.
As an answer to your post, the entirety of Ukraine is being attacked not just a single political ideology. If the country was in civil war and we were supporting one side then you would be correct.
Lastly, quit being a Russian apologist. The last 6 years of Trump supporters should show you exactly what is happening in Russia. There were talks of Trump even changing the constitution so he could continue in office. Sound familiar? Trump's kids continuously in the middle of illegal business dealings. Trump supporters don't care. Trump trying to use the DOJ to go after opposition. Don't care. Trying to pull us out of NATO. Don't care. Withholding aid to Ukraine unless Ukraine damns Biden's son. Don't care. Won't open books. Don't care. Openly talks about racehorse theory on national TV. Don't care.
Imagine you are a country that is not even a generation removed. Your people are hard and cold by nature, and seeing this new global world for the first time. All this western ideology is coming in. Parts of society that you despise are getting rights. You feel like the Russia you knew is slipping away. Then here comes this guy talking negatively about all the things you despise and fear, and preaching we are gonna make Russia Great Again. He brings out the flags, making you feel proud. Takes a hard, old school stance on laws, and even tries to reverse some of the ones you hated that got passed a long time ago. He temporarily props up the economy. You think you've found your guy, and ignore every other thing he is doing because he is fighting "for you" and he is "your leader". That's how Putin came to be where he is, but if it sounds familiar its the same playbook Trump ran(and is still calling plays from) here in the US.
Trump is/was following the Authoritarian playbook to the letter, and much like the population in Russia, Americans were swallowing it better than Bob Stoops can take one down. No matter what alarming shit happened or was said, you couldn't tell(and still can't) a Trump supporter anything. Much like Russia, there are large percentages of the population that think they are losing something. Whether its too many ethnic people, the LGBTQ community being allowed privileges, or any other ridiculous thing they choose to circle the wagons around, they feel as though they are losing the privileges they've been afforded. Trump, having watched Putin over the years, ran the same program here with much success. Make American Great Again is dog whistling, hearkening back to a time in the past when they were the only ones who got those privileges. People here ate it up, and had us heading in the direction of where Russia is now. Lucky for us we have A LOT of checks and balances built into our government.
The Russian people are to blame because they turned a blind eye to(and continue to) everything Putin has done. Information is coming in via soldiers, internet, loved ones abroad, and they are choosing to ignore it, even calling people traitors for suggesting their man is in the wrong. We can sanction them. We can go to war with them. At the end of the day the only way Russia changes is if the people rise up and make it so. Otherwise it will get leaders like this even after Putin is gone.
