The capture by U.S. forces of Venezuelan leader Nicolas Maduro and the killing in the operation of 32 Cubans assigned to protect him represent a major blow for the island’s revered intelligence services, experts say.

Fearful of betrayal by dissenters within Venezuela’s ranks, the leftist Maduro — like his late mentor Hugo Chavez — sourced his security detail in communist-ruled Cuba.

But the Cubans proved little match for the U.S. special forces sent by helicopter to snatch Maduro from a military compound after U.S. jets had pummeled Venezuela’s air defenses.
