Also, I'd point out that the attack on the King David Hotel was widely condemned by almost all mainstream Jewish and Zionist organizations, including the official Porto-army of Israel which turned into the IDF, and including by Ben Gurion, Israel's first Prime Minister.
Btw, if you want a fact that's sure to wow people - I'm fairly certain that, to date, the KDH bombing was the deadliest terror attack in the Palestinian/Israeli territory. (Excluding October 7th, of course, which I'd personally categorize as an invasion, not as a single terror attack.)

(As I've said: all sides here.)
NB: Skimming that article right now, the bombing seems to have pre-dated Hezbollah (generally given to have formed in 1985), though Iran's hand in affairs is fairly likely, and "Islamic Jihad" may have been a label adopted by Hezbollah or a nascent precursor group. The event is somewhat coupled to events in Palestine given the PLO's involvement in Beirut.
Again, it surprised me to learn this, and I find many others are similarly unaware. And again: the situation is complex and nuanced.
