Part of what is wrong with the view of American imperialism is that it is antithetical to our interests. We are better off when people are governing themselves. I'm sure there is some guy that will tell you that philosophy is no different from the Roman Empire's. Well, it is fundamentally different.

I certainly don't like a label that suggests I believe that the military is the solution to most of the world's problems.

China, in the future, is going to have even more nuclear capability than it has had in the past. I don't believe that they have anything to fear from the United States, and I frankly don't believe they do fear the United States.

The internal affairs of other countries has a big impact on American interests.

Obama, startled that components of government behave as interest groups, seems utterly unfamiliar with public choice theory. It demystifies and de-romanticizes politics by applying economic analysis - how incentives influence behavior - to government.

When our mothers are alive and healthy, they do extraordinary things... like the mothers of Plaza de Mayo, who marched in Argentinean plazas, defying the military junta dictatorship and demanding the whereabouts of their abducted children... or the Liberian mothers who faced down civil war armed only with T-shirts and courage.

I dream of an Africa which is in peace with itself.

Transparency in government, no less than transparency in choosing government, remains a vital national interest in a democracy.
