In the past few months I've had conversations with [British Chancellor of the Exchequer] Gordon Brown, [Russian President Vladimir] Putin, [Mexican President Felipe] Calderón and a number of U.S. Senators. They're all worried about protectionism. In the U.S. it's a huge concern. In Europe it's continuing - and in Germany it's growing. Look, we have this wonderful global market - as good as it gets. We have a lot of liquidity. What will throw the market off track? A terrorist attack, of course. But long term, protectionism could get us off track.
