The present american empire how to relly work

we know about the great empires roman and British,were already extractive. "The rule of the empire(2010)" book of timothy h parson . He describe the success of the Romes , the Omayyad caliphate,the Spanish in paru ,napoleon in Italy and British in India in extracting resource . And parson said his books introduction that he is really wonders whether Americas empire is really. after the eight years war and occupation of Iraq,Washington spend trillion of dollars with additional debt ,and without benefit of Iraqi oil. after tan years struggle by trillion of dollar against Taliban in Afghanistan , Washington has nothing to get except some drug tread for covert CIA operation fund.Americas war are so much expensive .Bush and Obamas war policy have doubled the national debt,and the American people have no benefit from it.So my question is, what is it all about? if you think deeply the answer is simple. American empire extracts the benefit of some special and powerful interest groups .thous who are rule America . wall street, the military security complex ,and Israel lobby group use the government to spend resource of American people for the serve of their power, profits and achieve any interest.after a decade the US military dose not control Afghanistan. SO their is no victory . Huge amount of American taxpayer have flowed into the armament industry. Larg number of Muslim have bombed , murdered , their economic and infrastructure destroyed . Obama and American people just think that the bombed and murdered of Muslim ,the American people victims of new American empire.
