On November 2, 1917, Foreign Secretary Arthur James Balfour writes an important letter to Britain’s most illustrious Jewish citizen, Baron Lionel Walter Rothschild, expressing the British government’s support for a Jewish homeland in Palestine. The letter would eventually become known as the Balfour Declaration.

Britain’s support for the Zionist movement came from its concerns regarding the direction of the First World War. Aside from a genuine belief in the righteousness of Zionism, held by Lloyd George among others, Britain’s leaders hoped that a statement supporting Zionism would help gain Jewish support for the Allies.

The influence of the Balfour Declaration on the course of post-war events was immediate: According to the “mandate” system created by the Versailles Treaty of 1919, Britain was entrusted with the administration of Palestine, with the understanding that it would work on behalf of both its Jewish and Arab inhabitants.

I would say the idea that anyone thought giving Britain or Zionist control in the first place was offensive, not only because they decided without the Palestinians that Britain would be entrusted with the administration of Palestine, with the understanding that it would work on behalf of both its Jewish and Arab inhabitants. Of course, that didn’t happen, and what could go wrong did go wrong, and decades later, genocide is taking place, and the question remains: where were the Brits? – Nativegrl77
