I don't have any idea who is going to win the IAS Freedom Medals this year, but I'd nominate the team of Scientology Volunteer Ministers who went to Java to help after the earthquake. Three months later, these VMs are still there.
They are helping at ever level of Java society to get the technology of L. Ron Hubbard into broad use to improve education, communication, help people overcome trauma and get an edge economically through administrative skill.
They are a very small team but they've made a major impact on a whole population and have taken it from a state of despair to one of real hope and confidence.
