War is a part of human nature, for some reason humans are born with an instinct to disagree, whatever the consequences maybe. From the very moment two neighbouring cultures collided it has never been a pretty site, disagreements lead to fight sand when this is on a national level. War is required, unfortunately war is always going to happen. In any shape or form!
No matter what. A country is going to want more power than required. And this is the exact reason war is inevitable, also third world problems consists of mistreatment of citizens. Something that must not be ignored. If a nation is allowed to mistreat its own people then human rights are being breached, the world will not be a happy place and if some country is invading and taking over another one then the world will go to bits, surely you don't want this to happen. And this is exactly why war is required whilst many lives are lost in its duration, it is for the greater good.
One of the many reasons war is a regular occurance is religious conflict, no matter what people are going believe different things. And if someone is going against your religion, you are not going to be happy! This is the main basis behind many wars such as ww2 and Hitler’s mistreatment of the jews, if he hadn't have been stopped the whole Jewish race could have been eliminated. And this is exactly why war is required. Another infamous example of this is the Gaza strip, The fight between the Palestinians and Israelis has become a worldwide battle between two conflicting religions. Also war protects many peoples human rights in many ways.
When a country's citizens human rights are being abused it is only humane to stand up for the people without a voice and if you don't help out your fellow people you are as bad as the ones doing the wrong. Such as in Afghanistan where there are many voiceless citizens who are being treated unfairly, and if you compare the unfortunate deaths that have occurred to the lives lost, you know war is for the greater good.Hitler was an evil man with almost complete power over a powerful nation. During the thirties, various other countries tried to appease him and by giving into his demands and ignoring the atrocities that were already beginning to be committed with the idea that if they did so, it would avert war because he would get what he wanted and be satisfied. Instead it gave him the opportunity to build an even greater war machine through that to cause millions of extra deaths than he and his Nazi Party would have been able to engineer if other countries had stood up to them sooner. And if Britain (and later other countries) had not stood up to the Nazis and said you won’t take our country, there would have been millions more deaths and more suffering. The same can be said of the World War II era Japanese government who committed equally unspeakable atrocities on their own people as well as the peoples whom they captured and conquered. While I do not believe that World War II was a good war because I don’t think any war is a good thing, I have yet to hear a credible argument that the world is not better off because people fought back against the evil that the Axis governments were trying to inflict upon the whole world and because of that I will say that it was a necessary war.
A final point I will make, is that without war the world wouldn't be like it is, just imagine if Hitler had managed to win the war where would the world be, i think it is pretty certain that we wouldn't have the privileges we have today.The way everyone thinks about things would be completely different, also the world's population would be considerably lower. Because he would have been successful with his extermination of Jews and gays and other distinctive groups. Also the whole world could have possibly been speaking German and being forced to do things. Without war all this could of happened.
So overall war is a requirement, even though it loses many good men and women a lot more are saved in the prospect and even though it tears families apart, it brings much more together. All meaning the same thing…
War is a necessary evil.
