And yes, if US and EU were serious about helping Ukraine win, this would have already happened back in 2022. Or better yet, back in 2014.

As it is, US & EU sanctions seem to be more of a theater mostly for the benefit of the population of those countries, so that their politicians can sincerely say that they "support Ukraine".

Depends on the claim - some are, some aren't. The problem obviously exists, but the coverup is good enough to make lots of people think that the war happens on another planet and doesn't affect them (e.g. gasoline export ban).
