I've been too busy to blog much this week, but I thought I"d mention that I've taken the plunge and signed up for Twitter (@StephenWalt). I'll probably use it sparingly, but who knows? Please bear with me until I get the hang of it. Brevity has never been my long suit, so this may take awhile.
Stephen M. Walt is the Robert and Renée Belfer professor of international relations at Harvard University.
