(3) Politically, presence of U.S. forces could hasten Commies to establish so called "representative government" in South Vietnam.
(4) Aside from offering Viet Cong a political target, US troops would constitute provocative military one, inducing VC to attack/harass it in manner/degree where issue might ultimately force American units active military campaign, or suffer defensive alternative of being pot-shot at to point of embarrassment.
(5) Presence of US troops could induce Commies to resort to related actions such as introduction of Red Air Force elements
