Like any internationalist, I embrace Scotland's interdependence and the advantages that such interdependence confers. But in international relations - perhaps even more than the economic sphere - there are major advantages to pursuing an independent policy that promotes Scotland's global interests. Indeed it precisely because we live in an interdependent world - one where markets are integrating and information flow is unstoppable - a world where the reality of climate change acts as a daily reminder of our reliance on each other - that independence matters. Interdependence is a welcome fact of modern global politics. What matters in the Scottish national interest - above all else - are the terms on which Scotland engages. The equality of esteem, of authority between nations matters more now than it has ever done.
