Obama and Romney: two visions of foreign policy

Foreign Affairs has given space to Barack Obama and Mitt Romney. From the summaries:

Obama -- "After Iraq, we may be tempted to turn inward. That would be a mistake. The American moment is not over, but it must be seized anew. We must bring the war to a responsible end and then renew our leadership -- military, diplomatic, moral -- to confront new threats and capitalize on new opportunities. America cannot meet this century's challenges alone; the world cannot meet them without America."

Romney -- "Washington is as divided on foreign policy as it has been at any point in the last 50 years. As the "greatest generation" did before us, we must move beyond political camps to unite around bold actions in order to build a strong America and a safer world. We must strengthen our military and economy, achieve energy independence, reenergize civilian and interagency capabilities, and revitalize our alliances."
