Interesting that you unrepentantly never admit when you're wrong about such elementary historical facts, but just move on to other aspersions and disparagements. Of course, you are still the product of your state education...wherever you happen to live. I will pray for both you and MarMema (yet another ugly American?), that you will seek after God in true humility, and seek for his will and grace for your lives....
Here, do a little research:
Nuclear Blast Radius
25 megatons: 10 mile radius, over 50% casualties, instantly.
1 megaton: 2.7 mile radius, over 50% casualties, instantly.
Oh yeah, 9 Megatons is just for a bunker....bs.
