Please answer the following question: I know that the answer to the question "Who was responsible for making sure the agreements were adhered to?" is in "On 29 November 1947, the United Nations General Assembly recommended the adoption and implementation of the Partition Plan for Mandatory Palestine. This UN plan specified borders for new Arab and Jewish states and also specified an area of Jerusalem and its environs which was to be administered by the UN under an international regime. The end of the British Mandate for Palestine was set for midnight on 14 May 1948. That day, David Ben-Gurion, the executive head of the Zionist Organization and president of the Jewish Agency for Palestine, declared "the establishment of a Jewish state in Eretz Israel, to be known as the State of Israel," which would start to function from the termination of the mandate. The borders of the new state were not specified in the declaration. Neighboring Arab armies invaded the former Palestinian mandate on the next day and fought the Israeli forces. Israel has since fought several wars with neighboring Arab states, in the course of which it has occupied the West Bank, Sinai Peninsula (195657, 196782), part of Southern Lebanon (19822000), Gaza Strip (19672005; still considered occupied after 2005 disengagement) and the Golan Heights. It extended its laws to the Golan Heights and East Jerusalem, but not the West Bank. Efforts to resolve the IsraeliPalestinian conflict have not resulted in peace. However, peace treaties between Israel and both Egypt and Jordan have successfully been signed. Israel's occupation of Gaza, the West Bank and East Jerusalem is the world's longest military occupation in modern times.[note 2]". Can you tell me what it is?
