At the end of world war 2, people realized the cost of such mass destruction. Not just people but politicians too realized the fact that they won’t survive another one. Almost half the population who were badly affected by world war 2, was just recovering from the first one. They knew, they learned by the hard way. They realized that unity is required. UN was formed so did EU, just as a precaution, just to reduce the bloodshed. And for a long time we thrived in peaceful world – of cause these times the war happened in somewhere else, but at home, most of the western countries felt safe. Perhaps as technology improved, people become less and less educated on how things worked, and how things work; they don’t need to understand, they only need to know how to use. Now they almost forgot what happened when the truce was broken – bloody war is a simple term back in the WW2 season, if it comes now, we have a whole lot of stuff to throw at each other. It seems, the only way to recover is not to look after our leaders, but educate the next generation about our past, educate our future to learn from the mistakes. Most of the leaders serve for their own small selfish cause. But the world is bigger than that. To call ourselves intellectual species, we shouldn’t just advance in technology, more than that, we should advance in humanity as a singular organism to conquer the future. The key to that is unity.
