I want to know the answer to the following question:
When did American military involvement ramp up in Vietnam?
All the background I'm provided with is that "The Vietnam War was a war fought between 1959 and 1975 on the ground in South Vietnam and bordering areas of Cambodia and Laos (see Secret War) and in the strategic bombing (see Operation Rolling Thunder) of North Vietnam.". Is that enough to answer the question?
Answer: no
