What was Kennedy's plan for Vietnam after sending aid proved to not be effective?

After sending aid to Vietnam and realizing it was not effective, President John F. Kennedy considered a more active military involvement to support the South Vietnamese government against the communist insurgency. He increased the number of U.S. military advisors and supported special operations, while also contemplating broader military engagement. Ultimately, Kennedy aimed to stabilize the South Vietnamese regime and prevent the spread of communism in Southeast Asia, yet he also sought to avoid a large-scale ground war. His approach was characterized by a mix of military support and diplomatic pressure.
