Give capitalism a chance to change Cuba
By Fareed Zakaria
In the midst of the extraordinary spectacle of Nelson Mandela's funeral – in a stadium with some 90,000 mourners, including more than 90 heads of government – a small gesture caught the world's attention. President Barack Obama moved to greet Dilma Rousseff, the president of Brazil. On his way, he shook hands with the person to Rousseff’s right. The photograph of that handshake ricocheted around the world. Understandably, because the man Obama shook hands with was Raul Castro, president of Cuba.Remember, the United States does not have diplomatic relations with Cuba, and has a tight trade embargo in place against the island nation. So, many wondered whether this handshake was the beginning of a great shift in policy.
