Should Nuclear Weapons be banned?

The use of nuclear weapons has always been a topic of sheer terror for everyone. Many countries are now considering banning the use of nuclear weapons. In this essay I will take a look at the advantages and disadvantages of nuclear weapons and come to a final conclusion on whether they should be banned or not.
On one hand, nuclear weapons indicate how strong and powerful a country is. The first and foremost criterion for other countries to consider you a strong and developed country is to have a good defence system, and nuclear weapons provide exactly that. Nuclear weapons are also useful because if a country or their enemies both possess nuclear weapons, then either one of them would be scared to launch a nuclear weapon, just in case the other country fired one back at them. Currently, there isn’t a major threat in the world of nuclear weapons but in the future there might be one, so countries should be prepared and armed just in case. In Scotland, there are a vast number of people employed in the developing nuclear warheads. If nuclear weapons are banned and removed, all these people will become unemployed and that will raise a new problem for the government to solve.
Another major reason to be considered is that once the technology for something has been introduced and invented; people are going to keep trying it out and cannot uninvent. So it is understood that countries might as well continue making nuclear weapons. Countries that possess nuclear weapons play a major role in the security of other countries; because they can protect the countries that do not have them. Furthermore, nuclear weapons are really useful because they can be used to threaten a country’s enemies and make them act in a certain way.
On contrary, the use of nuclear weapons is a horrendous issue. The world has only ever seen a nuclear bomb in action twice; at the end of WW2 when America fired it at Japan, in which 250,000 people were killed and entire cities of Hiroshima and Nagasaki were destroyed. Although 65 years have passed to this incidence, people in those two cities are still suffering from various diseases caused by the bomb and its harmful radiation.
Every year, there are billions of dollars invested by countries in developing their nuclear weapons. However, if those billions of dollars were in a good cause such as education or health care, the world would be a much better place to live in. At the moment, there are 20,500 nuclear weapons in the world. Research states that this amount of nuclear weapons is enough to wipe out the entire human race, many times over.
Many countries argue that nuclear weapons increase their security. Instead, if we think about it logically, this argument encourages other countries to invent nuclear weapons as well. This argument is capable enough to trigger another cold war between multiple countries and possibly and countries developing an arms race in competition with other countries. Nuclear weapons have not stopped any wars since 1945; instead they were the cause of the Iraq war, and the Cold war.
Moreover, Nuclear weapons are extremely expensive; $100 billion dollars are spent on them every year. This is the same amount of money needed for everyone in the world to have clean water, enough food, basic health care, and a proper education.
In conclusion, I think Nuclear weapons should be strictly banned and destroyed. The world has only every seen the terrors a nuclear bomb can bring once; and that one experience has been more than enough. Nuclear weapons should be banned so that our human race has a future. The fact that the current amount of nuclear weapons in the world can destroy the human race many times over is actually horrifying. I think that Nuclear weapons should not only be banned, but also removed and taken away from any country’s possession.
