There was no talking until the Oslo Accords of the early 1990's, because until then the PLO was focused on using terror and violence to destroy Israel. There were negotiations for 7 years during the Oslo Period (1993-2000) which fell apart because of Hamas terrorism and Arafat's duplicity and decision to reject talks and launch his terrorist war in 2000 (but these negotiations got the Pals control of 2/3's of Gaza and some 40% of the WB). Negotiations did not resume until around 2007-2008, when once again the Arab Pals walked away from generous proposals by Olmert. There have basically been no negotiations since, because Abbas is refusing to talk. So the claim by the Arabs and their supporters that they have wasted 60 years in negotiations is nonsense.
