Thanks for the email. Same offer if you are here:) It's interesting to hear your comments on economics - for someone like me, obviously with much less academic credibility than you, I almost see the two as inseparable, especially when it comes to the US and China. I think of history from the days of the Silk Route to the East India Company and wonder if it isn't mammon that is the engine of world politics. Just a thought. Hope you are having a good day.
