Hani Tahboub and two of his Warao staff

Venezuela, 2007

I saw the man with the machete first. He was leaning on the fat end of a downed mangrove that was blocking the way upstream. He stood on a branch chopping away, but his efforts had produced only a slight notch in the tree. There were three others waiting in the boat, the youngest resting the butt of an automatic rifle on his knee. Their uniforms gave them away as members of Venezuelan president Hugo Chavez’s National Guard—as notorious as the waters they patrolled. The State Department estimates that 200 metric tons of cocaine makes its way through the country annually, much of it through this vast river system, which extends into Colombia.
