Canadian parliamentarian and human rights lawyer Irwin Cotler talks about the importance of advocacy within the international community. Cotler describes his efforts against two of the 20thcentury’s most repressive regimes: the Soviet Union and South Africa under apartheid. He speaks about his experience representing former prisoners of conscience Nelson Mandela and Natan Sharansky and explains that, in both cases,it was tireless international advocacy that led to their release. While both of these regimes may have collapsed, Cotler emphasizes that the struggle for freedom has not ended, and he will continue to devote his life to human rights advocacy.
