This is the date that the UN mandated a State of Palestine and a State of Israel. This was the original "2 -state solution". Between Nov 29 1947 and May 14 1948 Israel chose David Ben Gurion to be their Prime Minister. On May 14 Ben-Gurion officially declared the State of Israel exists. During the same time period the State of Palestine did not choose a leader or declare their state officially and on May 15 1948 one day after Ben-Gurion's proclomation the State Of Palestine along with the 5 Arab armies of Egypt, Syria,Lebanon,Jordon ,and Iraq attacked Israel for the 1st time. They were repelled and Israel still exists today. Israel WILL NOT go back to pre-1967 borders because that is the same as Nov 29 1947. Palestine refused it then and cannot all of a sudden decide that is what they are willing to agree to in 2012.
