In the last several decades, the United States has spent a significant amount of resources to establish a worldwide presence diplomatically, economically, and politically. All this has resulted in significant disapproval from many nations, while the nations receiving aid generally are induced to pay for it diplomatically through alternation of their domestic and foreign policies. Justification: The general belief in the United States among politicians is that World Wars One and Two have demonstrated that the most powerful nation on earth has to make its presence known throughout the world.
