There's an additional problem: the US has little appetite for risking its own lives right now. For good or ill, the US spent two decades in military projects that are widely considered failures. Or at the very least, they failed to establish objectives at the beginning, and never clarified it. Going into Ukraine purely as a "defensive" effort would create another indefinite war. And maybe that's the right thing, but right now a lot of Americans aren't prepared to commit to that. They'll send money, and weapons, but not put people in harm's way without a clear indicator of what they have to do to get out.
