The vietcong were rebels in south vietnam who wanted to rid both north and south vietnam of communist influence. spread the catholic religion throughout vietnam. overthrow the communists who controlled the country. unify the south and north under a communist government.

The Vietcong were the Vietnamese fighters that the US was going against in the Vietnam War. At the time, containing Communism was one of the main reasons the US was even involved, so I’d say that the correct answer is that they wanted to unify the South and North under a Communist government.
