Usually, the opposite question is asked about Kennedy, or about less escalation or different (nuanced?) escalation if Kennedy had survived.
This question goes the opposite direction. What if, instead of withdrawing [mentioned at time, but not *really* on the table, standing pat with the Eisenhower training/aid/equip policy, or the historically adopted halfway house of sending in combat advisors with ARVN in the field, JFK acceded to the expert DoD consensus recommendation presented to him in 1961, to send in a limited commitment of US ground combat troops to assist ARVN against the VC, and a limited bombing campaign against infiltration routes in North Vietnam?
In OTL, President Kennedy *rejected* the advice of the Maxwell Taylor-Walter Rostow report of late 1961, which called for the the introduction of US ground combat troops, and beginning of a limited air campaign against North Vietnam. The report, which was endorsed also by the SecDef and Joint Chiefs, called for an immediate (so in early 1962) increment of 5,000 combat troops, into South Vietnam, but openly stated somewhere over 200,000 troops would be required ultimately. This would likely come after a period of gradual logistic build-up, barring unforeseen mass escalation or Chinese intervention on the Communist side, reaching the 200,000 ground troop level by early 1964.
What would have been the consequences in Vietnam, the US internally, and the global scene of the US introducing ground troop units into Vietnam in 1962 (two years before any complete PAVN units were introduced) and reaching over 200,000 troops by early 1964?
