War has been an active part of civilization since the beginning of humanity. Sometimes war is used for more selfish reasons, sometimes to achieve a more “noble” goal. Whatever the cause, humans have always found a reason to wage war, but with a price as high as human lives, why do humans still resort to war? There are many ways to explain this, but the only way war has been successful since is to protect more lives or the quality of life of more people who lose their lives on the battlefield. Because humans are prone to selfish behavior, they always want something that is not theirs and can often lead people to think that the only way to maintain their quality of life is to take from others. Then, when they invade to take what they think is theirs, the other party must defend themselves and their property, thus starting a conflict. War is inevitable because human nature is inherently selfish and there is a lack of global authority to control the impulses of power seekers. There are several major reasons why war is inevitable. One of them is the inability to control the impulses of selfish people and their desire to take what is not theirs. Another is that envy is a trait that is impossible to dismiss in some people and in some people. The last thing that makes war inevitable is people's instinct to protect themselves and their property. The world, at the time, lacks a universal authority to control the selfish impulses of the greedy. Everyone, at one time or another, wants something that is not theirs, but most people can deny these desires for fear of punishment. There is nothing in the world that punishes theft, so what starts with one man's selfish ambitions could lead to world war. The United Nations was built to act as the authority of middle of paper ......uel Kant. Immanuel Kant believed that if every citizen of the world contributed to justice, peace would be possible. The problem is that it is impossible to bring everyone on the planet together behind the same cause because: people have different perceptions of what justice is. Without a rule of justice or universal law, there is no way to enforce injustices in the world without war. In conclusion, with the constant conflicts the world faces, war is a huge cost in trying to secure peace. Unfortunately, this seems to be an ongoing cycle in which the human race is doomed to suffer. Most people seem to be opposed to this endless war, but as long as they are, people will think it's a way to get what they want, and that will always be a reality. Maybe one day there will be a way to stop the war, but for now it is an inevitable horror for human society..
