Ah yes. And you trust your government to do a perfect job stopping power companies from any such intentional miss-management, especially given such dire consequences? I don't, even though I trust my government quite far.

Because the Japanese government's failure to stop TEPCO from this miss-management is just as bad as any engineering oversight. And Japan isn't a third-world country. Japan runs a tight ship in most regards, tighter than the US and many EU nations. Other countries with a nuclear industry are far more troublesome: Iran, Pakistan, India, Ukraine, Russia, China... But if Japan can fail so spectacularly, all risk estimates around nuclear power are futile.
