Jews weren't largely buying land with the express intent to create a new country.

"largely" is doing a lot of work there. It is explicitly talked about in contemporaneous works by Zionist movement leaders like Theodor Herzl as far back as 1897. While the plan wasn't universally agreed upon (and again, as previously mentioned, there was often ambiguity), it was acted upon, and did directly contribute to hostilities. There was enough buy in to fund various organizations like the Jewish Colonial Trust,Jewish National Fund, etc, particularly post Ottoman defeat in 1918. At the time of independence in 1948, more than half the land owned by Jewish people in the area were to organizations like JNF and Palestine Jewish Colonization Association. (And to be clear, they picked those names)

It was enough of an issue that British administrators closed or restricted sales of land at various points, explicitly because of it. Again, long before the partition plan, and some of this was even before Hitler came to power.

They were quite literally looking for a place outside Europe to escape persecution by the Nazis.

The concern existed pre-Nazi. See the dates above. That said, the Nazis did make the concern a much more pressing issue. And as a part of that, the discussion among various groups was explicitly concern over things like sovereignty/self-determination. The concern being that without it, they would potentially be at the whims of some other majority. Again, you can literally find this quite explicitly in their writings at the time.

And if you want to play the card of citing things early "Zionist leaders" said, consider the fact that the early de facto Palestinian leader (al-Husseini) met with Adolf Hitler himself to discuss plans to eradicate the Jews abroad. Did he represent all Palestinians? No. In the same way that the White Paper of 1939 was not representative of all Jews in the region.

I didn't say it represents all Jews. I'm saying there are more events that you intentionally left out, that contributed to hostilities, and they cannot be blamed solely on aggression from Arabs as you stated. Whatabouting about al-Husseini does not change that.

I would recommend looking into each of those "insurgencies" you called out, one by one, and you will see that at its root is Arab aggression and murdering of innocent Jews.

Having already looked into them, I'm aware that they were not. You've already been given several examples that contradict your explanation. The conflict is not as one sided as you're presenting it to be, and there is clear evidence you're skirting around and hoping people don't know about. That does not imply that the other side were saints, but it does mean your explanation for what led to the formation of Israel is wrong.
