Analysis: High stakes for Cuba in Chavez's cancer battle
As Venezuelan President Hugo Chavez recovers in Havana from his fourth cancer operation, Cubans face renewed worries about their economic future if the country's top ally dies or has to step down from office.
Cuba has staked its economic well-being on the success - and generosity - of Chavez's self-declared socialist revolution, much as it did with another former benefactor: the Soviet Union.
Cubans vividly remember the great depression of the 1990s that followed the demise of the Soviet Union, and they worry about the communist-run island plunging into similar economic hardship if Chavez loses his struggle with cancer.
In the 1990s, they suffered through severe shortages of food, consumer goods and oil. Prolonged electricity blackouts made daily life miserable in what the government called the "special period".
