In today's "media," specifically AI prompts, it's all about how you ask the question.

In general, when I come across "wild claims of connections," I usually like to see if there is any established evidence for it (whether or not they include usable (convincing to a normie) sources corroborating the claims). Here's my first attempt at asking the question:

Prompt: "jacob rubenstein establish israel"

There is no evidence that Jacob Rubenstein established Israel. Jacob Rubenstein, an Orthodox rabbi who died in 2008, was known for his leadership in modern Orthodox Judaism and for founding the Young Israel of Scarsdale synagogue in New York. He served as president of the Rabbinical Council of America from 1997 to 1999.

The establishment of Israel refers to the founding of the State of Israel in 1948, which involved key historical figures such as David Ben-Gurion and other Zionist leaders. Jacob Rubenstein was not involved in this process.

It is possible there is confusion with another individual named Jack Ruby (born Jacob Leon Rubenstein), who was involved in the assassination of Lee Harvey Oswald, the accused killer of President John F. Kennedy. However, Jack Ruby also had no role in establishing Israel.

Therefore, Jacob Rubenstein—whether referring to the rabbi or Jack Ruby—did not establish Israel.

Bolded for emphasis. Clearly, within the usage of the rhetoric of the AI, Jack Ruby had nothing to do with the establishment of Israel.

And here's a second attempt:

Prompt: "jacob rubenstein (jack ruby) connections to the state of israel"

Jacob Rubenstein, better known as Jack Ruby, had indirect connections to the establishment of Israel through his associations with prominent figures in the Jewish-American underworld who were actively involved in supporting Zionist causes and the nascent Israeli state. Ruby was born to Polish-Jewish immigrants and was part of a family that maintained a strong Jewish identity, observing holidays and keeping a kosher home. He later changed his name from Rubenstein to Ruby, along with his siblings, partly to avoid the stigma of a recognizably Jewish name for business reasons.

Ruby was closely associated with Meyer Lansky and Mickey Cohen, two influential Jewish mobsters who played significant roles in financing and arming the Zionist movement before and after the creation of Israel in 1948. Lansky, in particular, was a key financial conduit for Israel and Mossad, facilitating arms purchases and laundering money for Israeli operations. Israeli agents were introduced to Lansky in the summer of 1948, and he permitted a $10,000 benefit for the Haganah at his gambling establishment, the Colonial Inn, declaring, “I’m at your service”. It has been reported that nearly 90% of Israel’s foreign arms purchases were channeled through banks connected to Lansky’s network.

Ruby himself worked within the Lansky syndicate and maintained ties to Cohen, who was deeply involved in Zionist activities and even boasted of sending arms shipments to Israel. Cohen had direct contact with Menachem Begin, the former leader of the Irgun, a paramilitary organization considered a terrorist group by the British at the time. These connections place Ruby within a broader network of Jewish mob figures who supported Israel’s military and financial needs during its formative years.

Additionally, Ruby reportedly served as an informant for the House Un-American Activities Committee (HUAC) in 1947 under his birth name, Jack Rubenstein, with Richard Nixon’s staff reportedly utilizing his services. Some accounts suggest that Nixon himself acknowledged knowing Ruby from that period. While there is no direct evidence that Ruby participated in arms smuggling to Israel, informant testimony links him to figures involved in such operations, including claims that he was involved in smuggling arms to Cuba with Donald Edward Browder, suggesting a pattern of illicit activity involving weapons.

Ruby’s personal motivations were also influenced by his Jewish identity. He was known to react violently to anti-Semitism and participated in street fights against the German-American Bund before World War II. His defense attorney, William Kunstler, claimed Ruby confessed to killing Lee Harvey Oswald “for the Jews” , a statement corroborated by Rabbi Hillel Silverman, who reported that Ruby made the same confession during a jail visit. Silverman, who led Congregation Shearith Israel in Dallas, noted Ruby’s irregular but meaningful engagement with the Jewish community, including attending services to say Kaddish for his father.

Thus, while Jacob Rubenstein (Jack Ruby) was not a direct actor in the political or military establishment of Israel, his criminal affiliations and personal convictions tied him to a network of Jewish mobsters who materially supported Israel’s founding, and his actions following the JFK assassination were framed by some as an expression of Jewish loyalty and defense against perceived threats to the Jewish community.

Bolded for emphasis, though I suggest it is all very relevant. All of the sources are secondary sources. I haven't dug into these sources, though I did look at the sources lists (if they existed). Looking over those lists several of them are primary sources and there are quite a few strong secondary sources as well. It's definitely a good place to dig further.

Here's the links for the AIs claims:

This is both a post about "how you frame your question matters," and, more importantly, further evidence of a solid link between the Rothschilds, Mossad, the CIA, the Jewish Mafia, the assassination of JFK and the creation of the State of Israel (along with numerous other interesting entities) all tied through the Economic Monopoly, Organized Crime networks, conjoined Intelligence Agencies, etc. This looks like a pretty good place to dig into pretty much everything; how the entire Cabal network is linked, what their broader goal is, and who's running the show (or was).
