You couldn't have funded jackshit with those funds because they were not funds, you by and large send over weapons that are about to be decommissioned and value them at replacement costs (which you would've done anyway), not their decommissioning costs (which would imply negative value).

As you were talking healthcare in another comment: The US spends just as much federal tax dollars per capita on health care as the UK spends per capita on the NHS. It's not that you're not spending the money it's that you'd rather shove it into corporate profits than actual medicine.

You know who's actually bankrolling Ukraine? As in quite literally paying the wages of state employees because their economy tanked and they have no tax revenue while simultaneously fighting a war? Europe is. And we're sending weaponry, old and new, not rarely stuff our own armies don't even have yet.
