"Cooler heads realize that such dire warnings from major media and world leaders are exploiting a decades-old propaganda campaign that has convinced the world that inside every nuclear reactor lies a mushroom cloud waiting to happen. Lesser known facts should alleviate some of the fear that reports from Ukraine engendered.

If such could be accomplished, what was the point of the Manhattan Project?"
