90% of US aid paid for weaponry from the US, for which, by the way, the Pentagon ripped-off the Ukrainians by delivering used weapons from US stockpiles while charging the Ukraine aid the full price for the newer, upgraded equipment supplied to US forces. So the Ukraine aid actually upgraded a lot of US military equipment.
If you want to look for corruption, look in DC, which will not go away even if all aid to Ukraine stops. They don't even need to launder any money: they steal it from us in front of our faces in those 1,000 page continuing resolutions.
And, steal from us while proudly announcing how much they are stealing. Every time Jerome Powell speaks of a 2% "inflation" target, he reminds us they will steal 2% of our wealth. "inflation" is theft, performed by printing - essentially "clipping" all existing fiat.
I got the wrong foreign country that we're giving billions away to? lol....What about that 10%? Tell me, which corrupt politicians we're making bank on those weapons? Who got the bribe money?
And who told you no cash was sent to Ukraine?
