It's all about power projection.
After the fall of Soviet Union, Ukraine all along is Russia's buffer to the West politically; their "elected" leaders are all Pro-Russian and anti NATO/EU. From Ukrainian peasant perspective, it means being "enslaved" by corrupted leaders and stuck in a country that is bound to never be developed into a free country.
Zelensky came along and got elected with the promise of making Ukraine into top tier free democratic country like rest of Europe. Putin bui song. So that's why Putin invaded. Imagine your underling suddenly 180 degree on you, you sure get rest of your gang to hoot the underling mah.
The joke is on USA. Because USA is one of the few countries to have supported the Orange Revolution (https://en.wikipedia.org/wiki/Orange_Revolution) which started it all but now that Ukraine is independent, they suddenly just dump Ukraine faster than a guy dump his mistress.
But okay la, USA people want to isolate themselves then so be it. The crux now is Europe and GB must support Ukraine if not they are next...

This remind me of those drama, the wife and husband all along fine. Then this 3rd party guy come and seduce the wife. Now the wife divorce liao, the 3rd party guy say I piak piak enough of you so I also gonna dump you.
Orange movement was supported by US and CIA. HK actually was a carbon copy of the so call civii disobedience movement before covid.
Fine, Zelensky was elected as the president because as a comedian he was always seen as a hero mocking the government and system and have the right image.
So reality check now, Zelensky has proven to be an incompetent leader which send hundred of thousands of citizens to death for nothing and now end up giving up lands to Russia and in debts to US.
Zelensky is stupid enough to believe because US helped him into power, US will also help him in the war against Russia. Delusional and politically naive... The majority Ukrainian who voted and believed in his bs make all Ukrainians paid dearly for their decision.
