In mid-November 2018, a Bible-clutching American evangelist trespassed onto the forbidden North Sentinel Island in the Andamans and laid eyes on the “world’s most isolated” indigenous people—the Sentinelese. “My name is John [Chau] ... Jesus Christ gave me the authority to come to you,” he hollered. The Sentinelese, who live in voluntary isolation, repelled him. The evangelist, however, was resolute to “declare Jesus” to the inhabitants of “Satan’s last stronghold.” And the rest is history.
