Japan's opposition demanded on Tuesday that a rising figure in the ruling bloc retract comments comparing their party's tactics in parliament to those of the Nazis in 1930s Germany. Taro Aso, 67, an outspoken former foreign minister, made the remarks Monday in a meeting with the president of the upper house, the opposition Democratic Party of Japan and news reports said. "Comparing the DPJ to the Nazis is a verbal abuse that completely lacks common sense," said DPJ Secretary-General Yukio Hatoyama. "We demand a retraction, of course." Aso, considered a leading future candidate for prime minister, apparently was repeating past comments drawing parallels between the opposition's recent boycott of parliament and Nazi tactics prior to taking power in Germany.
