A victim of Fidel Castro's mass round-ups of dissidents in Cuba has expressed alarm about the upcoming Jade Helm exercise, writing that he is 'worried immensely' about the military drill set to take place in nine U.S. states this summer.

In a letter to the editor of the Corvallis Gazette-Times, Larry Daley remarks that he was shocked to see video out of Fort Lauderdale which features military and police training together to arrest citizens and take them to internment facilities.

"It has been more than 55 years since 1961 and the Castro-ordered round up suspected resistors in Cuba. According to some press reports in excess of 200,000 were arrested during the Bay of Pigs," writes Daley.

"My youngest sister and I were arrested and taken to improvised holding facilities. We ended up in the huge Blanquita Theater. We tried to sleep under lights on the theater seats for days on end. There were bodies on the floor. The sanitary facilities overflowed with sewage."
