In terms of motive regarding the RFK assassination, though he publicly was very supportive of Israel, when RFK was attorney general under his brother, he seriously clashed with the Israel lobby. Grant Smith wrote:

Fulbright uncovered a massive network of financial “conduits” moving funds directed by the Jewish Agency in Jerusalem to [Israeli] lobby startup groups across the United States. 

Even as JFK attempted to place Israel’s Dimona nuclear weapons program under US inspection, RFK ordered the AZC to openly register and disclose all of its foreign funded lobbying activity in the United States.

The DOJ and AZC fought their secret battle as Fulbright’s hearings disclosed the immense proportions of the Israel lobby effort. 

Nathan B. Lenvin, a DOJ attorney who had been after AIPAC’s founder Isaiah Kenen since 1951 to continue registering as a foreign agent after he left the employ of the Ministry of Foreign Affairs took copious notes of the many meetings, AZC’s offers of limited registration and the DOJ’s counter offers.

But the law enforcement effort ended in tragedy.  JFK’s assassination … in Dallas meant RFK’s political cover for the prosecution was gone and his days at the DOJ were numbered.  He left to run for a New York senate seat. 

In 1965 the DOJ allowed the AZC to file a highly redacted and non-standardized FARA declaration in secret.  The AZC then shut down and transferred lobbying activity to AIPAC, which refused to register.

The anti-Zionist American Council for Judaism wrote to RFK about their fight against the American Zionist Council:
