Dear Sir or Madam,
I am afraid you are tilting at windmills and to some extent burying your head in the sand.
A dam failure half a world away away from me does not have a significant probability of harming me or the ecosystem I depend upon. A major radioactive release half a world away from me does. At this point it is possible, though hopefully improbable, that I will be required to leave my home at some point in the future, even though I live thousands of miles away (you may dispute the chance of this, but the news remains ominous and certainties are hard to come by). All of this because of poor decisions made by corporate bureaucrats from a completely different country (over which my fellow citizens have absolutely no influence through voting) a couple decades ago. Perhaps you can see why I am extremely concerned.
Holding the world to a standard set by a totalitarian government cutting enormous corners without benefit of oversight or design standards, in comparison with one of the most technologically and knowledgeable advanced countries and corporations supposedly under extremely strict regulations, is completely unfair. Obviously a bunch of idiots will harm far more people than those who make at least a civilized attempt at preventing catastrophe. The question is simply, did those in charge take adequate precautions, and what lasting effects will the lack of planning will have now and in future generations.
Let us place the blame squarely for both items in question upon the source: insufficient engineering on points of failure whose catastrophic degradations outside of design parameters due to unforeseen natural disasters caused enormous unforeseen consequences. Let us also recognize that the effects of these have spheres of influence. The dam failure killed a lot of people and nobody will argue that. However, a level 7 nuclear catastrophe will have international effects that far exceed local and natural ones for perhaps hundreds of years.
You may deplore those responsible for the massive dam failure, and I concur, and we can debate who should be held accountable, although that is pretty clear. This should not in any way diminish your admonition of those responsible for today's failures by people who supposedly have superior know how, and due to a democratic government as well as historical situational fact, the serious *obligation* to not completely cock it up while involving extremely dangerous and incredibly toxic nuclear materials that have multiple generational consequences. And if the worst were to happen, say, right next to the Pacific Ocean, what exactly would those extremely long term effects be.... we just don't know yet, and I sincerely hope we both agree those will not come to pass.
