But although Fidel Castro dominated Cuban political life for nearly fifty years, his illness hasn't created a leadership vacuum. His brother, Raul - acting president now for over a year - is credited with keeping the Cuban people calm and the government united. Raul Castro has moved his supporters into key positions, while the powerful Cuban army - which he leads - has been given a bigger role in overhauling the economy.

Many analysts think the transition to a Raul Castro presidency is well underway, even though his ailing brother insists he's being consulted on the key decisions. But the real test for the survival of the Cuban system will still come when Fidel Castro dies. This could be the catalyst for bottled-up social tension, or rivalry within the government to break out, even though observers generally think Cuba is more likely to experience a slow, orderly transition to a more open system.
