feels very odd to watch an American president do correct things for the wrong reasons.

Lol, war with Iran... A correct thing?

Sorry what? Can you clarify why it’s reasonable to lose part of your country’s sovereignty?

I hope u not gonna deny that US funded that overthrow in Ukraine

In 2014, while Ukrainians were busy rioting by tens of thousands - about their government abandoning the EU association treaty - most of the world was entirely unprepared for taking even a firm political position about the events. After all, Yanukovich was a legitimate president who had only recently resorted to violence. Nobody had expected a revolution over a trade agreement, but he sparked it by having the folks protesting at Maidan beaten and dispersed. If he had talked or compromised with them, history would be considerably different.

As for who eventually took advantage of the situation - well, it was Putin. He used the opportunity to occupy Crimea (while denying that it was occurring) and to start an armed insurrection in Eastern Ukraine (the initiators were well known GRU people, including the now jailed Girkin).

I'm not sure where you get your information, but your source is not competent on Eastern Europe. The US is a far clumsier creature than you imagine (perhaps you expect today's US to have the manners of the 1960-ties) while Putin's regime has rarely had any second thoughts, and has been quick to draw and fire, because there's only one brain making decisions, and he's been in the Kremlin for decades now...

so I can understand they don’t want hostile state right there, especially with nuclear ambitions.

Nuclear ambitions? Are you even aware that Ukraine gave away its nuclear weapons to a friendly Russia, at a time when nobody even imagined Russia invading Ukraine? In return, though, it received security guarantees, both from the US and Russia. It also handed Russia its strategic bombers - because why have them - and intercontinental ballistic missiles - because what's the use.

Before Putin entered the path of annexing parts of Ukraine, nobody had any reason to consider Ukraine and Russia to be hostile to each other. You can consult the old polls. The people considered each other brothers, until Putin exploited the confusion of a revolution in Ukraine, starting the invasion he's now trying to finish. During the years 2014-2022, he gradually became dictator in Russia and brainwashed people into considering Ukrainians enemies. His goal? Making Russia great again, and he felt Russia couldn't be great without the resources of Ukraine.

However today, after Russia has spent 1000 days grinding meat, I bet that several European countries do indeed want nuclear weapons - without admitting it openly, of course. Because apparently, conventional weapons don't really deter Putin.

Imo conditions for Ukrainians are more than fair - Russia gives them citizenship, all the native rights,

Sorry, but your sentence is laughable. Apparently, you are entirely unaware of the situation in the occupied territories, or in Russia. In Russia, you can get 5 years quite easily for criticizing the war. In the occupied territories, you just disappear if you get in someone's way. Even most of the fallen Russian soldiers just "go missing", so nobody would have to pay their relatives. The "native rights" of Russians at the moment are heading quickly towards rock bottom, and might only have some glamour if you offered them to North Koreans.

My recommendation: get informed first. And if your preferred way of getting informed is Facebook, Twitter or YouTube, then before going, be aware that such sites are algorithmically steering you towards material you're predicted to like and engage with. Encyclopedias where one is required to cite sources, and mainstream media (some of it anyway) where a person can be held responsible for spreading falsehoods - they exist for a reason.

Make sure to add some salt to your next mouthful of vatnik propaganda
