INTRODUCTION: It's an immense honor and a privilege to have been invited to participate in a tribute to Lou Henkin. Even if that were not the occasion, just the honor of sharing a panel with Judge Barkett and with Dean Koh is enough to overwhelm anybody and it does overwhelm me. I hope you will sympathize with me for having to follow them. It is especially overwhelming because as I look around the room, I see so many people who are much more deserving than I am to be here and to be honored in the way you have honored me in inviting me to speak today.
