Seven decades after the atomic bomb fell on the Japanese city of Hiroshima, a single pocket watch found amid the blast's debris serves as a reminder. It's stopped at 8:15, the time the bomb hit on the morning of Aug. 6, 1945.
Now a replica of the original watch and other artifacts found after the bombs hit Hiroshima and, three days later, Nagasaki, are on display until Aug. 16 at American University Museum in Washington.
A rosary, a sake container, a student's cap, 20 items in all, provide a personal connection to the tens of thousands who were killed instantly after the United States bombed the Japanese cities to bring an end to World War II.
It's estimated that at least 200,000 people were killed in the bombings.
But the book "The Bomb: A Life," by Gerard DeGroot, also cites a 1946 report from analysts who worked on the Manhattan Project. "The atomic bomb did not win the war against Japan," the book quotes the report as saying, "but it most certainly ended it, saving thousands of lives that would have been lost in any combat invasion."
The discussion continues to this day.
The university museum says on its website the exhibition is meant to "deepen understanding of the damage wrought by nuclear weapons and inspire peace in the 21st century."
To that end, both cities use their respective anniversary dates of the bombings to send letters of peace to leaders throughout the world.
In Hiroshima, temple bells sounded at 8:15 a.m. Thursday local time for a minute of reflection followed by events at the city's memorial park. Afterward, people released paper lanterns on the city's Motoyasu River to remember the victims.
Nagasaki will hold a vigil to remember the dead and other ceremonies in the Peace Park on Sunday.
The exhibition at American is free and open to the public; it is open 11 a.m. to 4 p.m. Tuesdays through Sundays.
