Remember the vast majority of the US aid to Ukraine was spent in the USA, given to American companies that manufacturer equipment and armaments. So this idea that the money is handed to Ukraine is bs. Thus the USA pays for various machinery, ships the old ones in stocks to Ukraine, and builds the new one for the US Army or whatever branch.
There is other aid too, like us companies helping ukraine rebuild its electrical grid as the russians attack it hoping to freeze out civilians. Its truly evil shit, and considered a war crime. The guys the USA is sidling up to. The ones who attacked. Who routinely target hospitals and schools. Unfuckingbelievable.
