query: What was the outcome of the Viet Cong's attempt to establish a governing apparatus in South Vietnam after the Tet Offensive?
answer: The Viet Cong failed to establish a governing apparatus in South Vietnam after the Tet Offensive, except in some Mekong Delta districts.  The breakup of larger Viet Cong units, coupled with the effectiveness of the CIA's Phoenix Program and the Chiêu Hồi Program, contributed to this failure. By 1969, there was little communist-held territory left.
