‘It’s the same every year. He talks gibberish and leaves,’ says one survivor after plagiarism app detects 93% match in speeches given days apart

Survivors of the atomic bombings of 75 years ago have accused Japan’s prime minister, Shinzo Abe, of making light of their concerns after he delivered two near-identical speeches to mark the anniversaries of the attacks on Hiroshima and Nagasaki.

A plagiarism detection app found that Abe’s speech in Nagasaki on Sunday duplicated 93% of a speech he had given in Hiroshima three days earlier, the Mainichi Shimbun reported.
