America's longest war has been by any measure a costly failure, and the errors in managing the conflict deserve scrutiny in the years to come. But Joe Biden doesn't "own" the mayhem on the ground right now. What we're seeing is the culmination of 20 years of bad decisions by U.S. political and military leaders. If anything, Americans should feel proud of what the U.S. government and military have

Controversy: was the Caribbean invaded by cannibals?
Columbus and subsequent chroniclers wrote about native peoples in the Caribbean who described being attacked by Carib cannibals. One argument against the veracity of these reports has centered on a lack of archaeological evidence that Caribs ever migrated to the Bahamian islands described in those reports. A 2020 archaeological study of skulls suggest the Carib would have been well established in
