He had reconsidered the Vietnam strategy —hundreds of soldiers were en route to the US at the time of his assassination.

1964 – Situation in South Vietnam deteriorates rapidly. In August, Gulf of Tonkin Incident occurs. The Gulf of Tonkin Resolution passed by the United States Congress gives Lyndon B.

1970 – President Nixon announces during a TV address, the withdrawal of 150,000 troops over the next 12 months. However, most people believe this not to be true and that it is merely a tactic to stop the massive anti-war movement. President Nixon sends US forces into Cambodia, causing widespread war protest in the streets, and plunging Congress into a session-long debate over Congressional war powers.
