Typical Cold-war attitude could be seen in here. But I'm very inclined to see a western-bias here. Every-single-thing in the documentary is mocking either Soviet or socialism. I one hundred percent believe that they must be the one to blame here for the tragedy.

But so hard to believe the irresponsibility, and so stupidity shown here questions their legitimately at being scientist.

Well, 'men' are stupid anyway.

And if all these are so true, then couldn't better explain the stupidity of Cold-War and atrocious acts done by 'both sides'.
