Our goal in backing Ukraine was to keep Ukrainians from being dead, or worse. And if you don't think there's such a thing as "worse", you weren't keeping up with the news from towns that the Russians took over.
It wasn't about weakening Russia. Russia is weakening itself, by putting so much of its economy and infrastructure into a fight that it can't win even with a much smaller opponent. It has destroyed its own army and demonstrated the inadequacy of its military technology.
It is, indeed, sad that the US has not solved its own homelessness and other problems. But pearl-clutching about that is just Russian trolling: we hadn't solved those problems before Russia attacked, either. And when Russia finally gives up in humiliation, we'll still have our own domestic problems. But not nearly as bad as the overwhelming incompetence, corruption, and horror of Putin's monstrosity.
