Quote from : The Next Decade: What the World Will Look Like Book

The reality is that the American people have no desire for an empire. This is not to say that they don't want the benefits, both economic and strategic. It simply means that they don't want to pay the price. Economically, Americans want the growth potential of open markets but not the pains. Politically, they want to have an enormous influence, but not the resentment of the world. Military, they want to be protected from dangers but not to bear the burdens of long-term strategy.
