Ukraine

Aid to Ukraine sits ~2.5% of the military spending. Most of that goes to domestic manufacture of replacement gear the US will keep if I understand properly.

I am not sure there's much to worry about there. Especially as the US military budget fails audit.

That is more concerning to me.

The US military literally loses more money between the couch cushions than we send to Ukraine
