Hiroshima Mayor Tadatoshi Akiba hit out here Friday at the "egocentric worldview" of the United States as well as moves in Japan to revise the country's pacifist Constitution.

"Ignoring the United Nations and . . . international law, the United States has resumed research to make nuclear weapons smaller and more usable," Akiba said during this year's Peace Declaration at a memorial service marking the 59th anniversary of the U.S. atomic bombing of the city.

"The egocentric worldview of the U.S. government is reaching extremes," he said.
