Should there be limits to how much financial aid a country in war gets, and who should decide these limits?

I believe that the concerns people have about the aid being sent to Ukraine are misguided. We aren't sending them cash, we're sending them military equipment. And much of the equipment we are sending them is outdated weaponry that's been sitting around since the Cold War. I have no problem with sending billions of dollars worth of this technology for Ukraine to use to fend off the Russian military, as even this outdated tech is sufficient to stave off Russia, which has proven to be just a paper tiger. These billions of dollars worth of warfare equipment don't have any benefit to the average American citizen, so sending it to Ukraine is not something we are doing instead of helping the average American. It's not a trade-off and we can do both.
