Hi, one of the most horrible and terrible events in the world history are two world wars which bring huge damage to the humanity. We all know about the harms of war but yet war is probable in many countries. It might be because of lot of conflicts in the world. While two sides are not agree and each one going its own way, and while there are countries want to force other countries unfairly war is probable to happen. But we need to know that now earth is a global village and any war can hurt all countries not just war participants.
