Nuclear weapons were actually not created for these, it was created to prevent wars, it was an INVENTIONS that was necessary during the heat of world war 2, if the NAZI has invented it first the world would won't be here today, and everything has it advantage and disadvantage. The world is not perfect as it is seen in movies. Nuclear weapons was necessary when it was created.

I have mentioned the word 'Proliferation', it means increase in stockpile of nuclear weapons. In fact, Albert Einstein himself warned it and had called for end of proliferation. Do you think it will help to prevent another war by just Stockpiling these hazardous weapons or will just end of humanity as a whole? By mentioning it was necessary at that time you are justifying 2 atomic bombs that were dropped was the right way to do for the end of 2nd world war. So many losses were occur and impact of that event was tremendous and horrible.

I am not justifying but it was a necessity, that was why it was called war, if that bomb was not developed then the war won't have ended, and imagine if it was the German that first built the nuclear weapons under Hitler, the world won't be here today, it always take hard decision to put an end to something. the war was going too far, it was even Albert Einstein that wrote the letter that the world need to develop such a weapon, when it comes to stockpiling of these weapons. That is a question for humanity to answer. Every country is Afraid of being invade by other countries. They need such weapons to push away agression and to put threat in the mind of thier enemy.

I have to say a lot but end up here with a question: Are you agree Science is both Blessing and Curse?

Science is a blessing,humans using it for negativity are the curse

So, is it ok to called Science as a BUISSNESS? What I see science itself is a factual having explaining the relation of cause and impact on matter. It's neither blessing nor curse actually. Human mind tend to interpret and used it in two ways either blessed one or curse one or both.

About preventing war, you can't prevent war, human has always been finding a way to put an end to thier enemies, even in heaven there was War. if every country has it way, they would also stockpile thier own nuclear weapons bro.
