Who said Russia were the good guys? I think you are missing the point. Flip a coin to decide who is worse, Ukraine or Russia. They are both horribly corrupt authoritarian states.
The main point is that we are the USA. We are literally falling apart and going bankrupt. We have to save ourselves before its too late. Not play arms dealer in order to make a few people super wealthy.
You do realise that the vast majority of aid stays in the US because it funds US armament contractors to build updated equipment to replace the more obsolecent stuff that gets sent to Ukraine? It also encourages sales of that equipment around the world from allies who are now concerned with a resurgent Russia. Europe is actually bleeding out more cash to fund Ukrainian non military aid that does not benefit domestic industry but goes directly to Ukraine.
