I'm going back to Oct 7 for my argument. You can go back to Oct 8 for yours but you'd be arguing in bad faith.
And you can trace that back to the Balfour declaration being unclear, and rabbis who started religious Zionism feeling entitled to the land, and antisemitic massacres in Europe that inspired Theodor Herzl to campaign for a Jewish state. Or even further back until you end up in Biblical times.
You can't just pick a start date and decide who is responsible for all this.
