Can someone please correct my essay? Nuclear weapons have been invented since the world war II. Many countries believe that such weapons can keep the world in peace. But whether they are global peacemakers or killing devices must be considered. Since the WWII, many countries have developed their nuclear weapons. The US used them to bomb Nangasaki and Hiroshima which put the war to an end. In this way, we might say that nuclear weapons are the global peacekeepers. Since then, many countries have been afraid of each other. Consequently, the world becomes even more integrated. Each country tries to form a relationship or an ally with one another in case another war might happen again. They are scared of everything which they are going to do because the believe that the future war is going to be fought with nuclear weapons. Only one of these bombs can destroy the small country like Thailand. Imagine countries like America and Russia, they own many of these weapons; they can surely destroy the whole world. Accordingly, the world still remains in peace and stability. But in the other hand, it can be said that people are just frightened of the results of the nuclear weapons, so they would rather stay quiet. Even though, nuclear weapons are great at keeping the world in peace, they are still killing devices. If the world had another great war, it would destroy the world into pieces with nothing left. They can kill thousands or billions of people in a blink of an eye. They are also taken time to make because they need advanced technologies and great amount of money. This means not all the countries have them. According to this, the ones who own the deadly weapons can take advantage from the others. For instant they might scare the countries that do not have nuclear bombs so they could get benefits for their self-interest. So, considering whether nuclear weapons are peacemakers or killing devices must take many things into account. Such weapons might be able to remain the world in peace but they are also the threats many countries use to frighten each other.
