The United Nations General Assembly this week overwhelmingly backed a resolution declaring the transatlantic slave trade "the gravest crime against humanity".

Three countries voted against it.
The US, Argentina, and Israel.

Slavery reparations: What does the UN vote mean?

African and Caribbean nations want countries which benefited from slavery to pay compensation but it will not be straightforward.

@petergleick it will be interesting to see how a financial amount is determined and who pays. With the Japanese Internment, there were clear records of the US government policies and records of the people who were interred and what they owned prior to internment. I imagine there may still be records of the slave trade and who was funding it, especially if involved royal houses or country governments. But it will be difficult to figure out how the payout would work.
