From Jiji Tsushin (7/11/2012):
Former Prime Minister Kan denies responsibility for self, argues against the Diet Investigation Commission['s conclusions]
In his blog post dated July 11, former Prime Minister Naoto Kan, of Democratic Party of Japan, commented on the Fukushima I Nuclear Power Plant accident by saying, "Almost all the causes for the accident had existed before March 11, 2011, the day the accident happened. And that's my conclusion." He denied his own responsibility, and criticized the response [to the accident] by TEPCO and the Nuclear and Industrial Safety Agency under the Ministry of Economy, Trade and Industry.
It is a rebuttal to the Diet Investigation Commission's report that concluded the excessive interference by the Prime Minister's Office with the efforts at the plant was "the largest factor that prevented [TEPCO from] arresting the progress of the accident and minimizing the damage". Mr. Kan plans to write about his conclusions on his blog for a while.
Mr. Kan sounds very familiar. Just blame the predecessors. It's the default position of the current president of the United States.
