My initial thought on it was that we never used a nuclear weapon for any purpose other than ending a war. Other countries want to use these bombs to gain power over the world, and many of the countries that have or want nuclear weapons are too unstable and have too many enemies to guarantee that neither one would shoot in anger.
Very good. You don’t need the help of others. Sounds like you’ll do fine. :-)
The world is "lucky" that the US had the first A-bomb.
If the Germans had it first, we'd all be speaking german.
If the Russians had it first, we'd all be speaking russian.
If Israel didn't have nukes, they wouldn't exist.
China has nukes - I think they see them mainly as a defensive weapon, and as a source of world prestige and power.
India and Pakistan nukes have probably prevented all out war between them.
Why does N. Korea need nukes? They can't even feed their own people. They only want them to threaten others.
Why does Iran want nukes? They're nuts!
