Members of an associated group, the May 19th Communist Organization, are still on the loose. Obama may have been a member of the group during his time at Columbia University in the early 1980s. The FBI does not seem to have made much headway under Obama in finding these fugitives, but it did put black terrorist Joanne Chesimard on its “Most Wanted Terrorists” list. We noted that the search for Chesimard, hiding in Cuba, could begin by wiretapping President Obama’s friends, Bill Ayers and Bernardine Dohrn, and other members of the Weather Underground. The Weather Underground helped Chesimard – a convicted cop-killer – escape from a New Jersey prison in 1979 and flee to Cuba.
A Vietnam veteran, Larry understood that the comrades of the Weather Underground were North Vietnamese Army troops and their communist terrorist front organization, the Viet Cong, operating in South Vietnam. The Weather Underground wasn’t anti-war, it was pro-war. A Weather Underground bomb factory discovered by the FBI in San Francisco had bombs, killing instruments, and communist literature, but no anti-war tracts.
Weather Underground members traveled to Cuba and even the old Soviet Union for advice and training.
