FILE - In this Nov. 12, 2011 file photo, the crippled Fukushima Dai-ichi nuclear power station is seen through a bus window in Okuma, Japan, as the media were allowed into Japan's tsunami-damaged nuclear power plant for the first time since the March 11 disaster. The U.S. had repeatedly warned Japan about vulnerabilities at its nuclear plants in case of a Sept. 11-style terror attack. It turned out Washington was right about the soft spots, but wrong about the enemy that would strike them. When nature unleashed its own fury on Japan last year, the elements Washington identified as most vulnerable in an attack, spent fuel pools, cooling systems, backup electricity, were the ones worst hit in Japan's disaster.
