On the surface it may appear that North Korea's nuclear bomb tests are merely political blackmail intended to intimidate South Korea, Japan and the western world. But there is much more to these tests than that.
How much radiation has North Korea unleashed?
I point out once again - The earth is quite round. There is no magic or political barrier to stop radiation from North Korea from entering the cells of little children around the globe.
Children all over the world are at greater risk for cancer because of the cruelty of political leaders who release radiation into our air and water. They are mass murderers.
But who cares?
