Hi Red Light Robot:
The fact that the Israelis shielded their nuclear program from JFK is enough to make you think they assassinated him?
This is insufficient for me.
The Israelis pissed off Republican President Eisenhower when they, the UK, and the French attempted to seize the Suez Canal, which he stopped.
A few years later the Mossad defied international law by abducting Nazi war criminal Adolf Eichmann from Argentina for trial in Tel Aviv.
Then the Israeli govt concocted a plan to assassinate JFK which would bring LBJ to power?
The JFK administration spent a lot of time dealing with Israel over their nuclear program, as the archives indicate: US national security archives
CIA and FBI would have suspected or even implicated Israeli complicity after Tel Aviv's previous bold international moves.
An intercepted KGB message from Mexico City to Moscow implicated the American rightwing as behind JFK's murder.
The Russians did not suspect the Israelis either.
As I strive to have an open mind, I will look into this line of inquiry further.
Below, Israeli PM David Ben-Gurion cultivating then-US Senator Jack Kennedy (D-MA):

Decades ago I subscripted/been a sponsor when assigned to Andrews AFB, but then they intended to put out an anti-American display [we bad] about our bombing Japan with the nukes that ended the war with Japan, and dropped my subscription, wrote a letter telling them as to why dropping them. So the have ben leaning left as far back as the late 70s.
Had to go to DuckDuckGo to find the info as all GOOGLE AI gave was about the 1995 one about the Enola Gay.
"In the late 1970s, the Smithsonian Institution planned a major exhibit on the atomic bombing of Hiroshima, which was later scaled back due to criticism from veterans groups. The final display featured a segment of the Enola Gay, the B-29 bomber that dropped the atomic bomb, along with a plaque and film about the mission."
