Passage:
The success of scientific experiments has led to an unprecedented development of human intelligence. In the Second World War, the power of the atom bomb defeated the unconquerable power of Japan in just a few moments. The wartime success of this power inspired all countries like America, Russia, Britain, France, etc., to manufacture such weapons that everyone started making dangerous and omnicidal weapons. Now, instead of manufacturing weapons to defeat the army and attack the enemy country with infantry, weapons are being made in the direction of destroying the country. If these weapons are used, most of the population and property of the enemy countries can be destroyed in a short time. Since some of these weapons have come into the museums/arsenals of almost all independent countries, their use will also become inevitable in the event of war. Therefore, the total destruction or majority destruction of the world will surely happen. That is why disarmament plans are being made. According to the direction adopted in the manufacture of weaponry, such advanced weapons have been made today, whose use makes widespread destruction appear imminent. Even now, ways are being sought to prevent testing and to stop the use of manufactured weapons. A terrible terror and fear of world destruction is working at the root of these efforts. Why are big countries making modern destructive weapons?
