I haven't said that much about Fukushima Daichi. I have two things to say.
First, if you read between the lines, it's very likely that the US Navy 7th Fleet, within hours after the disaster, offered to back up a super carrier to the plant, power up the pumps and give the technicians time to safely cool down the reactors into a non critical state. This would have allowed the situation to be dealt with, even though it was still serious, in a more organized manner and over a longer period of time.
The only reason I can think of that the Japanese refused this help is because of their long standing antipathy to American nuclear ships harboring in their ports and perhaps a misguided desire to be seen as able to deal with the disaster on their own and independent of American help. If any part of this scenario is true, then fuck them, they endangered the whole World for no reason.
The second thing is that nuclear power generation was originally entered into, by the major nations, in order to produce the plutonium necessary to make atomic weapons. That's all they cared about. They never bothered to do the work or incur the expense to make nuclear power safe. It could have been done. Fuck them.
