Where is the money going?
If we are sending weapons and ammunition to Ukraine, is the cost of those weapons being sent through either the military for the replacements for those weapons, to the Defense contractors to replace those weapons, or directly to Ukraine to purchase those weapons (and whatever else)?
I can sorta see reimbursing the US military for the cost of weapons sent to Ukraine, for the purpose of purchasing the newer systems which will replace those weapons.
In that case, Ukraine aid would actually be buying us new weapons and keeping the defense industry humming along building those, while the aging ammunition, and formerly cutting edge weapons systems were sent to Ukraine, sort of a back door weapons manufacturing program for us.
If however, that isn't the way this is working, that a significant portion of that money isn't going, in a roundabout fashion, to bolster our own defense with the latest systems and fresh ammo, the question is one of where the money is going.
That needs to be answered.
