The Palestine Liberation Organization (PLO) [...] is an organization founded in 1964 with the purpose of the "liberation of Palestine" through armed struggle, with much of its violence aimed at Israeli civilians.
Before that it was vanilla antisemitism, pogroms and massacres organized by the local Muslims, no different than how it was done in other places in the Middle East (or other places in the world). Some even were Nazi sympathizers/collaborators, like the Mufti of Jerusalem [2].
I wouldn't say millenia, but hundreds of years seems appropriate[1][2][3][4] ....
The "resistance" didn't start with the PLO. They are only the latest manifestation of a conflict going back centuries. It didn't start in 1948, or 1964, etc. It started long before that.
That's exactly what I wrote, so we're in agreement here.
Before 1964 it wasn't driven by a Palestinian national aspirations, it was driven by religious antisemitism/bigotry, and in a much lesser extent by pan-Arabism.
There were many massacres of the Jews (including of women and children) by the local Arabs. It wasn't something specific to Israel, it happened with many minorities all over the Middle East. My family has oral memories of one such massacre.
But I wouldn't call massacres of the civilian minority population - a "resistance".
I should clarify that I was ironically using that word. Basically the point is that this is part of a much larger history, that has pretty much nothing whatsoever to do with the formation of Israel.
Unfortunately, most of the people who've been tasked with bringing the "conflict" to an end cannot seem to fathom, or more importantly, actively choose to deny the existence of these prior elements. As they would completely undermine their (only) thesis.
Again, I hate giving Trump credit for stuff, but his approach of "lets make deals with parties willing to make deals, and ignore those who want to waste our time" has opened doors. It would be a tremendous shame if we walked backwards to the old (failed) peace processors viewpoint. With the current administration, I'd say that was inevitable.
Lebanon could benefit from this. So could the Pals. All they have to do is stop trying to kill Israelis and destroy Israel. I have little hope of this happening in my lifetime.
It's unlikely to be solved anytime soon.
