Ukraine is the replacement for Afghanistan gurl, they will keep sending stuff there until forever. Not way too much so that the conflict doesn’t end prematurely in favor of Ukraine neither too little so that Russia doesn’t win. The game is to keep this war for another 10 years and make Europe more dependent on US.
...or, the European countries (*cough* Germany *cough*) can invest more in their own military capabilities, allowing them to provide all the aid Ukraine needs for a complete victory, which would also strengthen their credibility in seeking strategic autonomy. As a bonus, the US will no longer feel the need to babysit Europe to protect itself.
