The British did not “hand over” Israel — the creation of Israel was a multidecade effort on the part of Jews since Hershel published his pamphlet in the late 1800s and the first meeting of the World Zionist Congress (1890.)
In the interlude, they tried a lot of stuff including simply offering the Sultan money for Israel, but I’ll skip to the British part…
A lot of lobbying and money was involved in getting the first Jew to ever be elected to British parliament also made the governor of “British Palestine” the year they got it from the Turks (1918.)
Thus marked the start of the “first Aliyah” where Jews around the world funded the purchase of land for young Jews to come and create Kibbutzes (self sustaining communities.)
Look up what they got up to in one of the first and largest Kibbutzes (manufacturing a lot of guns n ammo.) It’s a museum you can even tour today.
As Sun Tzu says, the pinnacle of war is to win without fighting and I see that so many people don’t really know about the creation of Israel, even though it is one of the most impressive feats of conquest (by Sun Tzus metric.)
