Yes, 60 year old Russian technology, government, and practices were horrible. And Fukushima's mostly-40 year old technology isn't
up to modern standards either. What is your point exactly? Perhaps you'd be just as likely to take Soyuz 1, which the astronauts
themselves helped find 203 structural problems with, than the Space Shuttle? I doubt it.
Cautionary tales? Yes. Demonstration of how things are likely to fail in future designs? Hardly.

If the locals let this happen, that would be very bad. But there are a number of ways to prevent and mitigate it. For one thing,
this would be a steam "explosion" of limited power. It ought to be possible to capture and filter the "outgassing", given some
time. In any case, even if the worst scenario happens, it will likely still not be an actual, rather than perceived, major disaster.
And it is still not indicative a likely failure mode of a modern design.
