Some of the motives and potential spoilers considered by Jerry Kroth in his theories about the Kennedy assassination include:

1. Motives:

2. Kennedy's intention to withdraw troops from Vietnam, which was seen as a threat to the military-industrial complex and the defense industry.

3. Kennedy's support for civil rights and desegregation, which was viewed as a threat by racist organizations and individuals.

4. Kennedy's efforts to normalize relations with Cuba and his backchannel communications with Fidel Castro, which angered anti-Castro Cuban exiles and the CIA.

5. Kennedy's plans to dismantle the Federal Reserve and return the power to issue currency to the U.S. government, potentially threatening the financial interests of powerful individuals and institutions.

6. Kennedy's opposition to Israel's nuclear program and his support for a Palestinian state, which could have angered influential pro-Israel groups and individuals.

1. Potential spoilers:

2. Government cover-up and suppression of evidence that could implicate high-ranking officials or agencies in the assassination.

3. Disinformation campaigns and the spread of false leads to confuse investigators and the public.

4. Intimidation and threats against witnesses or individuals with crucial information about the assassination.

5. Infiltration and manipulation of official investigations, such as the Warren Commission, to ensure a predetermined outcome.

6. The destruction or alteration of incriminating evidence, such as autopsy reports or witness testimonies, to conceal the truth about the assassination.

These motives and potential spoilers are central to Jerry Kroth's theories about the Kennedy assassination and suggest a complex web of interests and actors involved in the event. Kroth's research aims to uncover the truth behind the assassination and challenge the official narrative that Lee Harvey Oswald acted alone.
