This transition, this moment in history, is taking place because President Obama made a personal, fundamental decision to change a policy that didn’t work and that had been in place not working for far too long. I believe that’s leadership, and I appreciate that leadership. And President Castro felt similarly that it was time for a change. Both leaders agree that concentrating on the issues and possibilities of the future is far more productive than remaining mired in the past. And I would say as we look at the world today with conflicts that we see and even these negotiations taking place here in Vienna, it is important for people to understand that things can change, that leadership can be effective and can make a difference.
