How so? It's common knowledge that the nascent IDF absorbed terrorist organizations like the Irgun and Lehi into their ranks and gave them autonomy to operate as they had been. Leaders of these terrorist organizations went on to join the highest ranks of Israeli leadership. David Ben-Gurion being one of many (his Haganah cooperated closely with the Irgun and Lehi as they committed kidnappings, bombings and murders).

This isn't a conspiracy theory, it's widely documented by respectable historians.

That is true. Not sure why you are being downvoted. In fact, many of their victims were British citizens since it was under English mandate. It is impossible to reason with Israel apologists, for they are genocidal actors. It is what one would expect.

At the very least, I don’t see how anyone couldn’t call Begin a terrorist given the King David Hotel bombing, and he of course went on to become PM of Israel. The Irgun he led was also responsible for atrocities against Palestinian civilians like the Deir Yassin massacre, which Haganah definitely opposed.

Nonsense? Hyperbole?

I think you are either ignorant of the history of your country or you are ignoring the parts that don’t fit your narrative.
