Interesting comments. I’m not certain how accurate this is, but I’ve heard the U. S. only took about 5% of the slave trade here.
None the less, the U. S. is treated more like it took 99% of that trade.
Slavery elsewhere in the world--not important.
The "Trail of Tears" was a crime which killed thousands (under the auspices of Democratic Presidents Andrew Jackson and Martin van Buren). Stalin killed vastly more people with his evictions of certain ethnic groups during WWII--but no one hears about those crimes...carried out with much more cruelty than in the evictions of the Southeastern Indians. (Robert Gellately covers these evictions and much else in his recent book Stalin's Curse.)
