Yes, this.
The Ukraine war affects Europeans in Europe. While I'm on Ukraine's side, I still recall the Vietnam war (in which I was a uniformed participant). This is the time for the EU to step up, pay up, and man up. It's their fight.
Only after upgrading our United States Military (including trained and ready personnel and the very best in equipment and aircraft and aircraft carriers and missiles and every conceivable military advantage, should we even consider assisting a country that was not a member of NATO or an ally in any respect, ever.
And then, any aid we give would absolutely not include US troops, and absolutely, however, would include a thorough, comprehensive audit which would be real-time-published for all the world to see.
Any (any) corruption noted, deal is off, completely. And that's that.
This is like the 1930s all over again. There's no leadership in Europe. Russia will eventually conquer Ukraine. Maybe what remains will be a rump state in Kyiv.
