I can say the same about the russians I met. One of my colleagues comes from Russia (now living in California), she has a lot of relatives in Dombas region and she is really, really sad and feels ashamed about what her former nation is doing there. For her, it really feels like a civil war.
You have a point here, Steve. However, most of the countries you are naming have corrupt systems and the west wanted to remove a dictator and put in democracy. On Putin and the Ukraine (or any other country he invaded), it is the total opposit...
If you look back 20 years, Putin has named his plans several times. He tried to do it silently like with Belarus by supporting the local guy (which he also did in the Ukrain - until Selenskyj came to power, who then faught against Putins loyal elite in the Ukraine and made himself an enemy to Putin with that).
Putin is a spy from the cold war times. He saw the USSR brake down and hated what Gorbatschow did. He wants to turn back time 30 years at least (see his arguments with "since 1917, ..."). The whole Government exists of KGB members (they call the secret service differently now (GRU?), but it's actually the same organization). One of my business-partners was officer in the ex GDR military. He was in a special forces troup, training with the Speznas troups of Russia. He knows a lot of the now high class guys still (like the Chef of Police of Moskow). These relationships are life-time friendships... You are either in or you are dead (just like Piet said above - see the assissination of several people, even on german grounds!).
Putin has managed to put the "right" people (the ones that support him) into the chairs he needs the most support of from, has made them rich but always made sure they understand that HE controlles if they stay there or not... He tried the same with Ukraine and was on a good way, just like with Belarus. And then Zelensky came and destroyed his plans... I am not 100% sure why he actually wants the Ukraine. I understand that he wants to have full access to the Krim and that he needs the east-Ukraine for that. I also understand that he needs to go to Kiew to hunt for Selenskyj and that he will - most probably "accidently" - kill him. But as long as the west does not put hard sanctions in that really hurt the elite and the people in Russia or even fight back, he will not stop his expansion plans, that's for sure. He might make it smarter than Hitler did, but he won't stop...
I truely hope that he is smart enough not to attack any NATO nation, as this will defenitely start WW3.
