Which countries receive the most foreign aid?
Since World War II, $960 billion, or over quarter of all US foreign aid, has gone to five countries: Israel ($312.5 billion), former South Vietnam ($184.5 billion), Egypt ($183.7 billion), Afghanistan ($158.9 billion), and South Korea ($120.7 billion), after adjusting for inflation.
Followed by a nice graph. 25% to these five countries means 75% to other countries. And of that $120 billion to ROK, $30 billion was sent in 2018-2020. That leaves $90 billion spread over 78 years.
