(a) The Geneva Agreement of 1954, decided to divide Vietnam into the North Vietnam and the South Vietnam. The North Vietnam was under the Communists led by Ho Chi Minh.
The South Vietnam was under the emperor Bao Dai who was later overthrown by a coup led by Ngo Dinh Diem.
Diem established a repressive and authoritarian government. Anyone who opposed is called a Communist and was jailed and killed. His dictatorial rule was opposed by the National Liberation Front (NLF).
The NLF got the support of Ho Chin Minh government in the North and began to fight for unification of the country.
Worried about the increasing strength of the Communist Party, the US decided to intervene decisively, sending its troops and arms. As a result, Vietnam turned into a battlefield.
(b) From the given statement, I have learnt the values like sacrifice for the unity of the motherland and courage.
