Inept dictators: how low can they get?

Some months ago the dictator from Zimbabwe, Robert Mugabe, accused the CIA and Britain of being the culprits of the country’s severe cholera outbreak. A disease, which is endemic to Zimbabwe due to the lack of good quality water and of appropriate health measures, became, according to the African butcher, an aggression of imperialistic countries against Zimbabwe.
A few hours ago the eternal Cuban dictator Fidel Castro denounced the U.S. for introducing the swine flu to Cuba by relaxing the travel limitations of U.S. nationals to Cuba. Castro claimed that the U.S. was sending to Cuba all its cases of the flu!
Castro also criticized tourism in the island as being an agent of disease.
In a similar line of reasoning a few days ago the Venezuelan dictator Hugo Chavez explained the severe shortages of electricity and water in the country as a result of the “great prosperity of Venezuelans” under the revolution that has led to “much greater demand”.
Dictators all over the world are trying to explain their failures in the most ridiculous ways.
Some of their explanations, no matter how bizarre, are taken as the truth by the masses. But, for how long? How stupid can the people be?
