Inventions, ideally, are result of needs and necessities of a certain generation of humankind. Human beings prospered and progressed over time because of his inquisitive nature and the ability to explore. Discoveries and inventions helped them to know more about the mother earth and made them to make their stay on this planet more comfortable. Needs and necessities of different ages and times encouraged humankind to come up with new inventions, however, some inventions simply originated to serve the whims and fancies of some men in authority who abused their influence and knowledge to invent something which put a questionmark on mere existence of human race on this planet. An invention without which this world would be a much better place is the invention of weapons of mass destruction also known WMDs. A weapon of mass destruction is a nuclear, radiological, biological, chemical or other weapon that can kill and bring significant harm to a large number of humans or cause great damage to man-made structures (e.g. buildings), natural structures (e.g. mountains), or the biosphere.

These weapons were developed initially by industrialized nations liks United States, Japan, Germany etc as a weapon of self defence to deter the enemy against any possible aggression and attack (Deterrence theory of international politics). However, in due course of time these weapons emerged as a threat to the very existence of human race on this planet. The deterrence theory failed to prevent wars and battles between nations and rather led to beginning of an arms race between nations. India and Pakistan, 2 south asian neighbours developed nuclear weapons in 1998 but still had a war in 1999 and still have skirmishes on their borders on almost daily basis. The application of nuclear bomb by United States against Japan, use of chemical weapons by Germans against Jews in concentration camps made the world to realize the ferocity and dangers of these weapons. More recently, the use of Chemical weapons in Syrian Civil War had brought the world to brink of another war when US tried to intervene in order to maintain the sanctity of Chemical weapons convention.
The world have realized the uselessness of these weapons and tried to control, ban and regulate their usage through conventions and treaties like Chemical Weapons Convention (CWC), Biological and Toxin Weapons Convention (BWC), Partial Test Ban Treaty, Outer Space Treaty, Nuclear Non-Proliferation Treaty (NPT), Seabed Arms Control Treaty, Comprehensive Test Ban Treaty (CTBT, has not entered into force). These weapons not only are capable of killing millions of lives but also affect future generations, cause irreversible and irreparable damage to environment, drain resources of nations on non-productive activities. Secondly, there is an imminent threat of misuse of these weapons by terrorist organizations and anti-human elements that can use it to kill thousands of innocent lives. Threat of possession of such weapons was a major reason for US attack on Iraq. Thirdly, such weapons lead to power struggles and pose a danger to establishment of world peace.
Fourthly, even poor nations spend a considerable amount of their scarce resources on production and storage of these weapons instead of using these resources for the welfare of their poor and undernourished citizens. Thus, based on the arguments above we can easily conclude, this world would have been a much better place, had there been no weapons of mass destruction. After all, the ever more sophisticated weapons piling up in the arsenals of the wealthiest and the mightiest can kill the illiterate, the ill, the poor and the hungry, but they cannot kill ignorance, illness, poverty or hunger. Wars may be fought with weapons, but they are won by men. It is the spirit of men who follow and of the man who leads that gains the victory. It is high time that the world shall bid goodbye to WMDs and make this world a much better place to live in.
