Last week Secretary of State Hillary Clinton testified before the House Foreign Affairs Committee, and I had the opportunity to raise some of my concerns regarding US foreign policy and the costs of our interventionism around the world.

Many observers claim that the recent overthrow of governments in northern Africa and the Middle East will result in more liberty for individuals across those regions. I sincerely hope this proves to be true, but history is replete with revolutions that began as a cry for freedom against oppressive governments but ended badly. There are no guarantees that Egyptians, Tunisians, or others will be better off after these heralded regime changes.
