there is some truth to what you say, at least “just enough to keep Ukraine alive as long as possible but not to actually let Ukraine win”.
However I would disagree with over-generalised statement “Nobody actually cares about Ukraine except for russia”. Poland, for example, very much does not want to have common border with russia, esp. after this war. While US has a luxury of being able to ignore what’s happening it is not the case for some (most?) EU countries. Which also explains why some contribute enormously when comparing their contributions to respective country’s GDP. Ukraine independence also can be used by US as leverage against russia in the future, so while not humanitarian in principle, US has huge interest in Ukraine status.
There is a chance for Ukrainian win on battlefield without foreign soldiers, but it means lots of equipment. That window is quickly closing and then, yes, the only way to move forward will be foreign intervention.
you’re either misguided or malicious. Have you been to Ukraine? Have you seen what Russia has done to Ukraine over decades? What “special link”? It is as special as link between Jack The Ripper and his victims. russia is very much interested in restoring empire that includes Baltic states and middle asia etc.
russia had a chance at retaining Ukraine in it’s orbit prior to 2014. If they’d spent same amount of money they did on destabilisation of the country, on development instead, promoting Ukrainian culture etc. they could’ve had Ukraine forever. Honest. Before 2014 there was plenty of pro-russian sentiment in the country to pull it off as old crimes got forgotten and pain dulled. But from 2014 onward it became impossible.
At present if russia wins, either retaining stolen territories or grabbing some more - it will create destabilized zone that nobody in Europe wants in their backyard. russia is not there on humanitarian mission, and itls been made clear - they are on extermination mission. Like they have been multiple times before.
