I'm on my phone, so the history lesson is going to be pithy.
The Jewish insurgency in mandatory Palestine was prompted by British indications that it was going to create a multi-racial, democratic state in Palestine, as they did in many of their other colonies once they departed. I believe there was a policy white paper published but I don't recall the name.
After substantial British civilian/government worker deaths at the hands of insurgent bombs (ie. King David Hotel bombing), the British retreated and gave it to the UN, who did the partition.
> Palestine had its last election in 2006 and chose a party that literally killed its opponents.
I may be misremembering, but I believe a large reason elections haven't been held since then was because the party elected in 2006 was ejected in a coup by the party supported by the US and Israel.
So, 14 years since an election in Palestine, and Netanyahu has been prime minister for 14 years.
