This is a puppet government of the US that was installed in 2014 after they overthrew a Russian puppet government. Of course the previous US administration gave tons of support - Obama's people installed Zelensky, so Biden continuing the support makes sense. Biden's family has also made a lot of money in Ukraine under the current regime, so it was personal for him. As for Europe, this is existential for them and it's cheaper to spend Ukrainian lives on this than their own. What is missing is any other international support from parties who aren't directly interested in this conflict, like India pressuring China to stop supporting Russia.
Where is it wrong, though? Here are a few pointers:
Ukraine was Victoria Nuland's project. Her CIA had a huge hand in the protests against Yanakovich (who was, in turn, an asset of Putin's GRU), and she personally had a hand in negotiating with Yanakovich on behalf of the protestors. You should read about the events in Ukraine in 2014. That overthrow led to the retaliatory capture of Crimea, where the US and EU apparently did not learn their lesson about how much of a madman Putin is.
As for the Biden Ukraine connection, I'm sure Hunter Biden is just secretly very talented at managing oil companies, which is why he was put on the board of Burisma in 2014, after Nuland's little coup. I believe the "10% for the big guy" quote was in reference to this deal, too.
As for this being an existential threat to Europe, I'm not even sure you need to be given the facts about having a madman like Putin edging closer to your borders, while also depending on him for energy.
Finally, on supporting your puppet governments: it's basic game theory that you should do this. Otherwise all the other ones (see much of Latin America) get overthrown.
>They are doing fine with him there, and he has not done well at gathering support internationally
I really do admire your ability to live in reality that is not at all correlated with base reality. And from an Iranian as well. I noticed that Trump and his team do this a lot as well, along with Putin. What do all of these have in common?
I really hope that Zelensky doesn't arrive back home with a bad case of novichok or polonium.
