History was my favorite subject at school and still now I learn something new or more details almost on daily basis. One incident is caused by the multiple factors and it triggers more serious one. The first image reminds that human history has consisted of never-ending series of war. War is cruel, but fighting in the Middle Ages was one-to-one battle. Now unmanned drones can do indiscriminate murders. Why can't people create a new world by learning from the past mistakes and human follies?
