On 31 March 1947, Irgun set light to the oil refinery at Haifa, starting a fire which blazed for three weeks. In May, it attacked the prison at Acre, freeing a large number of inmates.
If I'm not mistaken, one of the prisoners they freed was a 19 year-old Menachem Begin, who was also one of the guys who blew up the King David Hotel.
It's an interesting history, and it's not the history we're being sold.
