On the first day of the Soviet withdrawal from Afghanistan in May 1988, an Afghan soldier hands a flag to a departing Soviet soldier in Kabul. "This was the first time journalists had full access to Kabul," Robert Nickelsberg says. It marked his first year covering Afghanistan. "It was a historical turning point for the Cold War and actually foreshadows the chaos that will descend on the country." (Courtesy of Robert Nickelsberg/Getty Images)
