Haim Arlosoroff not assassinated

Have we ever discussed the effect on Zionist history if Haim Arlosoroff had not been assassinated on the beach in Tel Aviv in 1933? Would he someday have become Prime Minister of Israel? He was after all a leading figure in Labor Zionism (which was the dominant political current in Israel for the first quarter century of its independence) and was younger than both Levi Eshkol and Golda Meir, both of whom became Prime Minister. https://en.wikipedia.org/wiki/Assassination_of_Haim_Arlosoroff
 
I once wrote a ATl series of vignettes in Italian about him surviving the assassination attempt and becoming a major figure.
The sketchy TL was extremely optimistic and wankish in that he would have been able to become a major political figure within the yishuv, steering its political trends into a way less confrontational position toward the Arabs (and the British).
In that TL, Palestine became an indipendent state within the Commonwealth in 1939 as a binational state, Arab and Jewish, based upon a carefully crafted compromise where Jews get unrestricted immigration while renounced to the project of Jewish nation-state.
Palestine therefore attracted a lot of Jewish scientists and other refugees that would otherwise prefer the US or other destinations (as they did OTL when given the choice), with the result that Palestine is the first country to have the Bomb, using on Germany to force an earlier end to WWII, I think in late 1944. The country then becomes the pivot for a "Semitic Union" comprising most of Middle East, North and Northeast Africa, and Malta, which makes for a lot richer and stabler area.
Thinking about it now, it was of course pretty wankish and unrealistic in many regards (even an independent, binational, peaceful Palestine full of European refugee physicists would almost certainly lack the means for a Manhattan-project level undertaking, even if both Einstein and Fermi end up in Tel Aviv, which is a lot less likely in itself than I had supposed then).
However, Arlosoroff was clearly poised to raise high through the ranks of the Zionist movement, and was likely to support and reinforce a less confrontational relationship with the Palestinians.
If the Arab Revolt is managed differently thanks to his influence, a binational state of sorts may be (barely) possible, and he would likely be a very important player in its politics.
