No body gives you power but it is taken from the people by those that need it. It is taken from the poor, the rich, middle class, religion, ethnic groups,weaker countries etc.If you need power especially politicians and world power countries,these people can go to any length to make sure they get that power. Check out what is happening in Russia and Ukraine ,Isreal and the Palestine. Each country is showing power either by technology or man power.
Power they say is not "served a la carte". Whoever needs power should be ready to fight for it, and in this fight, a lot can go south. Most of the crisis in the world as of today, is basically because of the quest to conquer opponents and get power so they can control. so a lot of times, this crisis happens not for the good of the common man on the street, but for personal aggrandizement and ego for those in the leadership position. So if the weak, the poor, the middle class and religious leaders wants power, they should get ready to also swim in the political dirty waters.
