SPRINGVILLE, Tenn. (AP) — Gretchen Catherwood’s son, 19-year-old Alec, was killed in Afghanistan fighting the Taliban in 2010. As she watched the news over the last two weeks, it felt like 10 minutes ago. As the American military left Afghanistan, the Afghan military put down its weapons, the president fled and the Taliban took over. On Facebook, she’d seen someone declare “what a waste of life and potential.” As she exchanged messages with the others who’d paid the price of war, she worried its end was forcing them to question whether all they had seen and all they had suffered mattered at all.
