The plight of the two former Green Berets who were caught last May trying to infiltrate and overthrow the Venezuelan dictator Nicholas Maduro continues.

In July, U.S. diplomat Bill Richardson failed to secure the release of Airan Berry and Luke Denman.

The two men had been caught on May 4 as they were attempting a daylight infiltration by fish boat into Venezuela. They were the second wave of mercenaries of the operation. The first wave, comprised of Venezuelans, had been compromised on May 3. The whole scheme to arrest Maduro was planned by Justin Goudreau, another former Special Forces operator, and his company Silvercorp USA.

The mission, titled Operation Gideon, was doomed to fail from the start as Goudreau himself had tweeted about the infiltration as the mission was taking off.
