Fareed Zakaria: Why Liberal Democracy is Worth Fighting For

Why is a nuclear peace deal between the U.S. and Iran key to stability in the Middle East? What would the global consequences of a full-scale trade war between China and America be?

Fareed is also the author of "Age of Revolutions: Progress and Backlash from 1600 to the Present," and a columnist for The Washington Post.
