In the post world battle II era there were fewer wars (no third world war because the second world war occurred just twenty years following the first), today countries engage in dialogues to be able to resolve problems somewhat than blindly declaring conflict against each other. Following the explosion of the first nuclear bomb by the US on Japan in Nagasaki and Hiroshima the planet saw the damage the bomb triggered eradicating over 200, 000 people in the two cities and folks who were afflicted by the bomb passed on because of rays and the near future generations were deformed at delivery. The explosion of the bomb terrified the world of the results of the bomb, no-one not the pilot of the plane transporting the bomb possessed any idea what would happen once he drops the bomb. He later composed a publication about the time during WWII, when the bombs exploded and he regretted the actual fact that he carried out the operation.
The Nuclear deterrence theory is whenever a country which owns a nuclear arsenal threatens its adversary country (also a nuclear armed country) that it will retaliate if attacked. This theory is a technique which is used to avoid armed conflicts between the countries. Types of this is during the cold warfare (when this plan was first implemented on a nuclear level) both the USA and the USSR used this plan however this never led to the utilization of nuclear weapons. Another (recent) exemplory case of this is India and Pakistan (in 2001 the President of Pakistan Pervez Musharraf got threatened India that it could use its nuclear weapons in the event India problems Pakistan) these countries utilize this strategy against each other. but both countries have never involved in a nuclear conflict against one another.
The final number of countries with nuclear weapons has risen to 7 the United States, Britain, Russia, China, France, India, Pakistan. However Israel has neither accepted nor denied the fact that they possess nuclear weapons although some analysts assume that they do.
After 1945 the nuclear "bomb" hasn't been used again against a country. China built its nuclear arsenal in order to become a regional power and India built its weapon in order to threaten its enemy Pakistan. Pakistan also built its tool in its defence, fearing a possible nuclear attack from the neighbouring India. It has been stated that Israel has generated a nuclear arsenal to be able to beat the risk of the Arab countries like Iran and Egypt whose Leader Nasser possessed threatened to assault the country in those days. Since the countries have built their weapons, there's been no serious war since each nuclear equipped country concerns that if indeed they attack the adversary country, they'll also undergo so, somewhat the ownership of nuclear weapons has prevented a major battle from the countries. However there has been nuclear standoff's between countries like India and Pakistan in the later 1990's and early on 2000's. Additionally it is said that both the countries acquired detonated their nuclear missiles prepared to be fired.
Today people also dread that the nuclear weapons may land into the incorrect hands example terrorist groups that might use the weapons for their personal gain and bomb their foe countries this could lead to a typical nuclear war that can harm the countries and lead to the fatalities of millions or even vast amounts of people.
Israel has grounds to create a nuclear tool since it is surrounded by enemy territory. Ever since the neighbouring countries have become aware of the actual fact that Israel has turned into a nuclear power, there has been no major or direct warfare by countries like Egypt and iran who always threaten to harm Israel.
Also during the cold battle period, there is no direct conflict from the USSR and the united states except for the mujahedeen battle during the overdue 1970's to the 1980's. Even then your USSR refrained from utilizing their nuclear weapons against Pakistan and the united states fearing retaliation from the USA. These are occasions that have proven that nuclear deterrence has averted nuclear issue against countries.
This theory stimulates proliferation since once a country offers a nuclear weapon, they'll always try and enhance their weapons(to be able to feel safe) and make duplicates, examples of this is both Pakistan and India who've conducted multiple checks of the missiles trying to boost their current models. Also countries like the US and Russia build missiles that can counter nuclear disorders.
I fear for the future of the world today, the 6 billion people living upon this globe today, if countries shed their nuclear weapons then the world will be a safe place again. I fear that this won't happen I dread that in case a third world war breaks out, it will lead to the devastation of our world resulting in over the billion deaths and the near future generations of those affected to be deformed because of the radiation( all it needs is a spark that can be brought on by an accidental activation of the nuclear weapon by a particular country and the country damaged would retaliate resulting in a nuclear war or if the leader of a region possessing the tool makes an irrational move by attacking its foe would also lead to a nuclear battle ). It might take us back again to the Stone Age and destroy our civilization for the reason that, over one thousand nuclear missiles would be detonated all around the world resulting in destruction of land, lack of human life. Also the long-term effects may be deadly producing a change of the environment because of hyper global warming, food lack due to damage to agricultural land causing it to be infertile in fact poisonous. Therefore what needs to be done is that the nuclear equipped countries should make a decision before it is too past due and regret like Albert Einstein ( who encouraged the then American President Roosevelt to build up the atomic bomb before Germany succeeds in creating the atomic bomb) the consequences of the nuclear bomb, therefore all the countries should take this problem seriously and really should avoid overlooking it by eliminating and dismantling almost all their nuclear weapons and make the world a nuclear free, a safe world once again!
