exile, where refugees constitute more than half of the Palestinian people. They were also afraid of the loss of representation of the refugees in the UN. In Resolution 67/19 November 2012, Palestine was at last awarded non-member observer State status, but the General Assembly maintained the status of the PLO. ′Non-member observer state′ status By September 2012, with their application for full membership stalled due to the inability of Security Council members to 'make a unanimous recommendation', the PLO had decided to pursue an upgrade in status from "observer entity" to "non-member observer state". On 29 November 2012, Resolution 67/19 passed, upgrading Palestine to "non-member observer State" status in the United Nations. The new status equates Palestine's with that of the Holy See. Diplomatic representation The Palestine Information Office was registered with the Justice Department of the United States as a foreign agent until 1968, when it was closed. It was reopened in 1989 as the Palestine Affairs Center. The PLO Mission office, in Washington D.C was opened in 1994, and represented the PLO in the United States. On 20 July 2010, the United States Department of State agreed to upgrade the status of the PLO Mission in the United States to "General Delegation of the PLO". Secretary of State Tillerson in 2017 determined that the PLO Mission broke US law prescribing the PLO Mission from attempting to get the International Criminal Court to prosecute Israelis for offences against Palestinians, under penalty of closure. On 10 September 2018, National security advisor John Bolton announced the closure of the PLO Mission; Nauert, a U.S. Department of State spokeswoman, cited as a reason Palestine's "push to have the International Criminal Court investigate Israel for possible war crimes." Peace process Initially, as a guerrilla organization, the PLO performed actions against Israel in the 1970s and early 1980s, regarded as terroristic activities by Israel and regarded as a war of liberation by the PLO. In 1988, however, the PLO officially endorsed a two-state solution, contingent on terms such as making East Jerusalem capital of the Palestinian state and giving Palestinians the right of return to land occupied by Palestinians prior to 1948, as well as the right to continue armed struggle until the end of "The Zionist Entity." In 1996, the PLO nullified the articles of the PLO's Charter, or parts of it, which called for the destruction of Israel and for armed resistance.
