It's not only about the money either. The even bigger blow is the whole 180 the US government has made, now actively aiding Russia instead of Europe. If it was just about the money, it would be a bit easier to understand (though still a big blow to the mutual understanding of what is worth defending in the world). If it was about the money, the US would happily _sell_ equipment to Ukraine and let the EU foot the bill. That doesn't seem to be the case though.
