Do you believe that there are more than 20,000 nuclear weapons around the world? The communists used false inter-continental missiles in their military parades in order to scare their enemies and create confidence on their people... It's an ancient political strategy to seem more powerfull that you are in fact! If USA had only 50 pumps, they wouldn't be sincere with North-Korea or Iran... They will tell that they have 10000!! and if they have 10000, they will tell that they have 20000!... Another point is that creating this kind of weapons is very expensive, but storaging them is astronomically expensive! Do they spend thousands of million dollars per year storaging that thousands of weapons when they are going to use them maybe once or twice times? It's not good for the ecomony... And an atomic destruction doesn't have a economic profit... you can't use them in a country that you want conquest... so, if you need to use them to sacare your enemies, you will need less than 10... I don't try to say that there are no one, I only say that there aren't so many as they say... What do u think?
