What group posed the biggest threat to the south vietnamese government?

n November 1963, President Ngô Đình Diệm of South Vietnam was deposed by a group of Army of the Republic of Vietnam officers who disagreed with his handling of both the Buddhist crisis and the Viet Cong threat to the regime.

The Kennedy administration had been aware of the coup planning,[3] but Cable 243 from the United States Department of State to US Ambassador to South Vietnam Henry Cabot Lodge, Jr., stated that it was US policy[4] not to try to stop it. Lucien Conein, the Central Intelligence Agency’s liaison between the US embassy and the coup planners, told them that the US would not intervene to stop it. Conein also provided funds to the coup leaders.[5]

The coup was led by General Dương Văn Minh and started on 1 November. It proceeded smoothly as many loyalist leaders were captured after being caught off-guard and casualties were light. Diệm was captured and executed the next day along 

after the civil war, and with the termination of slavery, the south was faced with a big problem; what was supposed to happen and how they were supposed to deal with the freedom and the rights that black people and freed slaves had gained as a result of the north defeating the south and forcing the end of slavery. first, most, if not all, of the workforce of the south came from slaves and they did not have an option to replace the loss of said workforce. second, particularly in the south, people were convinced that black people were lesser, less intelligent, less capable and less smart than whites. this posed a huge problem for them. also, southerners were faced with another issue; freed slaves now had a say in how their lives would be lived and the right to politically choose the way they would be governed. people in the south did not want to accept this, none of this and this opposition and the conflicts that arose from it, not to mention the afereffects of the war, forced the congress of the time to enact and enforce the reconstruction plans that had been proposed by president andrew johnson.
