Unless you want to barter with your medical provider using cold war era weaponry, it's not a direct comparison. Most of the "dollars" in aid Ukraine receives is equipment. There have been cash payments mostly for (allegedly) humanitarian purposes, and I won't begrudge them that.
Also the Israel aid is vouchers for them to buy US military equipment. Now whether we should support a genocidal nation at all is a question worth considering, but it's never stopped us before.
At this point it stopped being your money a long time ago and became your debt and your children’s debt and your children’s children’s debt. Got to love unhinged unbalanced generational national debt.
