Fidel Castro signed over his dictatorship/power of Cuba to his brother Raul before undergoing surgery Monday night.

The Cuban leader said he had suffered gastrointestinal bleeding, apparently due to stress from recent public appearances in Argentina and Cuba, according to a letter read live on television by his secretary, Carlos Valenciaga.

“The operation obligates me to undertake several weeks of rest,” said the letter. Extreme stress “had provoked in me a sharp intestinal crisis with sustained bleeding that obligated me to undergo a complicated surgical procedure.”

Castro said he was temporarily relinquishing the presidency to his younger brother and successor Raul, the defense minister, but said the move was of “a provisional character.”

Cubans all across Miami and the U.S. started celebrating upon hearing the news. No one should party too hard because his brother Raul is more radical and crazy than Fidel is.
