Well, when you find out that everybody may have been telling you lies, you just have to verify everything you're told.

I tend to think the Russkies were justifiably concerned that the DS/Neo-Nazis would rip the lid off that melted nuclear reactor. But I did have the same concern as you initially. “What’s underneath that thing? Maybe it’s not nuclear at all?” But I recall back in the day when the Soviets were lying to everyone that a meltdown had even occurred, yet countries nearby were reporting alarming levels of radiation increase.
