What led to the establishment of Israel, was British political and military support for the colonization of Palestine by European Zionists. No amount of bobbing and weaving will change the facts. Without British military suppression of the native people's attempts to block European (Zionist) immigration and the establishment of colonial infrastructure was what allowed the Zionists to establish their settler colony.
So in essence you are saying there would be no Israel if the British hadn't prevented the Arabs from massacring the Jews ("the native people's attempts to block European (Zionist) immigration"), but in fact the British, for the most part, didn't interfere. Every time there was an attack on Jewish communities by Arabs that was successfully fended off, British soldiers would search the Jewish community for weapons and confiscate them without taking any action against the Arab attackers.
It was precisely the British refusal to prevent "the native people's attempts to block European (Zionist) immigration", that is to massacre the Jews, that led to the formation of Irgun in the early 1930's to protect these Jewish communities, and it was the British refusal to prevent "the native people's attempts to block European (Zionist) immigration", to massacre the Jews, that persuaded the Jews, who had previously only wanted a Jewish homeland with self government in what was then Palestine under British hegemony that they could only live safely if they had a state of their own. Israel was made inevitable by Arab/Muslim xenophobia, which is a core value of Arab/Muslim culture, and by European greed and cynicism, which are core values of European culture and by the remarkable courage, determination, commitment and ingenuity of these early Israelis who had returned home after being away for so long.
