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 is earned by force and anyone that isn't deserving of it by taking it forcefully won't get it, even if you use your influence to take it forcefully from the poor or anyone in the society there will always be someone in the crowd that would be bold enough to stand up to you and question the way you abuse your power, so even if you power is taken there is always a rebelious person in the crowd.Some Politicians earn power through deception, corruption, lying, abuse and forcefully from weaker countries
