On November 2012, Palestine Authority(PA) was recognized as ``non-member observer state`` in UN General Assembly. The voting was 138 in favour, 9 against, 41 abstentions. PLO has been accepted position as a non-member observer entity on 22, November 1974. PLO or PA was non-member observer entity in UN for a long time. Although PA was not recognized as perfect sovereign state, there is an implication in being accepted as ``non-member observer state`` in UN General Assembly. If PA wanted to become a recognized sovereign-state under UN system, U.S.A, a permanent member of the UN Security Council that has veto power, has to recognized it as a member state in UN Security Council. Why Did U.S.A refuse the recognition of PA as UN member state? This study aims to analyze Obama government`s foreign policy to Israel-Palestine problems. I has reviewed the Israel-Palestine Peace process before analyzing Obama government`s foreign policy to Israel-Palestine problems and peace proposals, and then analysed Obama government`s Israel-Palestien policy, especially Obama`s address, ``New Middle Eastern Policy` on 19, May 2011. According to this analysis, Obama government has sought, and will pursue its national interest in guarantee of ``Israel security`` including Israel`s border problem. But I think that there are some possibility of policy change because of pressure of international organization in the near future.
