Atomic weapons did change the way people looked at the world.

Atomic weapons did change the way people looked at the world. The WW ll generation SAW what people on all sides would do and feared what they would do now that they had Atomic weapons. Until a workable counter measure is created that fear remains. Yeah I know "Ban the bomb" The problem is that most of human history says that simply wont work without a world government and what if as history also shows you end up with a Hitler of a Stalin? Sure might get a George Washington...but if ya dont where are ya going/ Mars? Or, what if you do if ya "ban the bomb" and Joey hides a few of his till you dump all of yours? All hail KING Joey! That FEAR, I suspect is the main reason that the world has been so unstable, and it is a world wide fear, since 1945 and until we get either:
A. An effective counter weapon.
B. Useful space travel
C. A Constitutional world government
It is not going to change. Yeah. I know that there is a chance that we may blow ourselves and civilization away; but I set the odds very very high against that. The people running things are not fools and they have too much to lose and they know it.
History also teaches that people generally act in what they see as their own self interest.
