Israel/Palestine is an example of the failure of British post-colonial government policy
Britain failed to reach an agreement between Jews and Arabs in the region and withdrew in 1947, allowing the problem to descend into violence. This has lead to numerous wars, terrorism, ethnic tension and a break down of human rights in the region over long periods of time. This is a left over problem of British colonial rule, which the whole world seems unable to find a suitable resolution for.
During World War One this region was under the rule of the Ottoman Empire, and the British promised to recognise Arab independence in the area in return for Arab assistance to British forces, fighting against the Ottomans. Following the First World War and the fall of the Ottoman Empire, the British Empire took control of this region as “Mandatory Palestine”, seen as a betrayal to the Arabs in the region. In 1917 the British government made the Balfour Declaration, a public statement to support a national home for the Jewish people in Palestine, and in 1923 Britain gained consent from the League of Nations to control the peoples of the region until a time when they were stable and “able to stand on their own” .
During this period of British control nationalism in both the Jewish and Arab communities increased, both against the British and each other respectively. This lead to the Arab Revolt in 1936 and the Jewish insurgency in 1938, both targeting the British occupation of the region. Trying to address the situation the British Government held the London Conference of 1939, where they proposed a limit of European Jewish migration to Israel and a limit on Jewish land purchases in the region, which prompted further outrage. Following this extremist Zionists organised further attacks and the “Aliyah Bet” the process of Jewish illegal immigration into Palestine.
Following the Second World War these ongoing tensions descended into a state of civil war. To address this, the newly formed UN adopted the Partition Plan for Palestine in 1947 and carved up the country, this did not quash the violence and British control disintegrated the following year. Even though the British double crossed both sides, it was only due to Jordan and Egypt that Palestinian territory was protected in subsequent wars in any way. The British made conflicting agreement to both communities during the First World War and then failed to resolve the problem they made for themselves, and therefore failed as an effective authority in the region. The blame for this problem undoubtedly falls on the British as it was created by them.
