According to this report in Guardian and reproduced in The Hindu, CIA tried to bump off Fidel Castro several times and still couldn't. The report says, CIA tried to get him 638 ways and still was not successful with the last known attempt being in 2000.
So, what does it tell us? Either of the two things..
- Fidel Castro's security is fool proof and nothing could touch him. Not even the long arm of US.
- Effectiveness of the much vaunted CIA. Given some of those 638 tries never left the drawing board and was spread over 47 years. Even assuming 50% of the 638 were actually executed, it is still too many attempts and speaks volumes.
