The item in the list which was NOT a justification for increased US involvement in Vietnam:

Explanation:

North Vietnam never was aligned with the United States.  The US was aligned with and fought on behalf of South Vietnam.  North Vietnam was controlled by a communist government and was seeking to unify Vietnam under communist control.  

US foreign policy in those years was one focused on fighting communism.  Domino theory was a major idea in US thinking at the time.  Domino theory proposed that the spread of communism in Vietnam would result in other countries in the region falling like dominoes to the influence of communism.

The event that sparked a major increase of US involvement in Vietnam was the allegation of attacks on US naval ships in neutral waters in the Gulf of Tonkin.  The Gulf of Tonkin Resolution was a measure passed by US Congress that allowed the US President to make military actions, like increase troops, without formal declaration of war.  The resolution was passed by Congress in August, 1964, after alleged attacks on two US naval ships in the Gulf of Tonkin.  The key wording in the resolution said:

That resolution served as a blank check for President Lyndon Johnson to send troops to whatever extent he deemed necessary in pursuance of the war.  Between 1964 and the end of Johnson's presidency in 1969, US troop levels in Vietnam increased from around 20,000 to over 500,000.

- "the civil rights movements"

- "following the american civil war and abolition of slavery, the united states entered a period known as reconstruction, during which black americans continued to suffer from disenfranchisement, racial segregation, and economic oppression. beginning in the early 1950's, black americans launched a series of major campaigns of civil resistance, emphasizing the need for nonviolent protests and civil disobedience."

"such as the montgomery bus boycott of 1955-56, a campaign launched by rosa parks against the policy of racial segregation of the public transit system in alabama. “sit-ins” became popular across the american south, particularly in greensboro, north carolina, increase national sentiment."

- "the counterculture movement"

- "counterculture began to develop in the united states following the rise of conformity in american culture during the 1950s. by 1963, youth, particularly those of the white middle class, began rejecting the cultural standards and normality of their parents, opting for progressive attitudes instead. the movement gained momentum as the civil rights movement became increasingly successful and as the u.s. military intervention of vietnam began to take a negative turn."

"hippie counterculture moved further into popular culture following the summer of love in 1967 when thousands of people came together in the haight-ashbury neighborhood of san francisco. along with greenwich village in new york city, haight-ashbury became a hub for the counterculture movement."
