briefly: what is vietnamisation?

Answer 1

Here's a quote taken directly from a website, 'history learning site' (try googling it)
Vietnamisation was the term used by Richard Nixon to describe US policy towards South Vietnam in the later stages of the Vietnam War. Vietnamisation was Nixon’s desired policy to enable South Vietnam to take a greater responsibility for the war while America started a planned withdrawal, while at the same time supporting the government in Saigon in its fight against the NLF.'

Hope this helps :)
