WASHINGTON – They fought the deadliest conflict in human history, but seeing it memorialized, even 70 years later, brought back a flood of emotions for a group of World War II veterans visiting Washington from Arizona. They were part of an Honor Flight, which brings the dwindling number of veterans from that war to see the World War II Memorial on the National Mall. “We’re too quiet about these ugly things. And war is ugly,” said one veteran at the memorial.But while the trip was sobering – and included visits to Arlington National Cemetery and other monuments – it was also a time for catching up for the veterans, who said simply that their service was necessary.
