The goal has absolutely nothing to do with tearing Russia apart. It's what we learned now

1. Ukraine will owe us BIG TIME for all of our weapons
2. They still need Russia for fuel. So does the surrounding nations so no Russia will absolutely win and subsequently fall on its own considering Europeans don't like having children. ( old people don't buy stuff and can't work)
3. We are able to see how fast we can ship equipment across the world and watch it fight a conventional military which protects our national security.
4. America doesn't need Europe, Europe needs America. Nato is basically a way to save money on not having an army. America is slowly starting to see how useless it is to keep up a pace to stop nazis and communists. Both regimes are almost certain to never happen again. You know with the whole average European age being like 40 something.
