Why did british change their support in favor for the Jews?

The British shift in support for the Jews during the early 20th century was influenced by several factors, including the geopolitical landscape following World War I and the Balfour Declaration of 1917, which expressed support for a Jewish homeland in Palestine. Additionally, the rise of Jewish influence in international finance and politics, alongside a desire to gain favor with Jewish communities globally, played a role. However, British support fluctuated over time, often balancing competing interests in the region, particularly with Arab populations.
