'A love letter wrapped in pain'

Hope is mandatory. Pretend to be human. Go. That's how author Rachel Goldberg-Polin says she made it through the 328 days her Israeli American son Hersh Goldberg-Polin was held in Hamas captivity after the attacks of Oct. 7, 2023. Rachel talks with The World's Host Marco Werman about her book, "When We See You Again." It chronicles her son's abduction and murder, and why she says she still feels blessed, lucky, grateful and in pain.
