 Presidents who want to have a more restrained foreign policy, if you think of that ship of state as an airplane and you get in and you put your hands on the controls of the plane and you think you're going to take it in a different direction, all these structural forces start buffeting the airplane and send you in the same direction as your predecessor, which is another way of saying, I do not think the United States is going to stop being a hegemonic power anytime soon, although I would like to see a more restrained foreign policy.
