In the days leading up to his speech Wednesday to the United Nations General Assembly, Palestinian President Mahmoud Abbas had promised something big—a “bombshell,” he told reporters. He did not exactly disappoint: Abbas used the speech to announce that the Palestinians would no longer be bound by the Oslo Accords, the historic 1993 agreement between Israel and the Palestinian Liberation Organization that created the Palestinian Authority. The agreement contained a set of interim arrangements, giving the Palestinians a small measure of autonomy in the occupied West Bank and Gaza, and was supposed to last five years, at which point a final peace treaty would be signed between Israel and Palestine.
