Despite most part of the experts constantly have said, the 21st century would be a marc of the human glory (politicaly and economicaly). The century has come with challenges that still would be easely found two, three hundred years ago. like, eliminate the poverty, fight against plagues and deseases that still keeps spreading all over the world, like aids. and , Fighting for lands, which seems to be the reason for a running to get fully armed.
In fact, to fight for lands use to walk on side by side with the human evolution since the very beginning. Thousand years ago, civilizations such as Romans and Persians abandoned their regions and leave, searching for lands (and taxes) creating an efficient enviroment of sustainability of its regime. And it worked, but, only before they use their legions to slaughter another thousands for its own good.
What there is behind all of this? Nicolas Machiavel, (The Princip) an important figure of the renaissance guide us through a cruel and dfinitive reality of the man while he is on the power. That the fight for power is the main "colera" that bring down kingdons and states. Evil and Kindness is just a point of view to prevent the result that most part of humans, want in its subconscious.

Realizing that, other countries would easily take away countries that would be consumer of their products, The murdered of Archduke Ferdinand was just the drop on the ocean, to start the war.
As much as what happened on the world war I, the world war II, the seeking for market was melting up former relations between countries. Quckly, Nazism and Fascism were spreading their values through the countries and the mind of people. People who were totally confident on their actions. Big Constructions could build up their countries, places where inflation and production were bringing down their economy and their faith.
