security apparatus" must "begin sustained, targeted, and effective operations aimed at confronting all those engaged in terror and dismantlement of terrorist capabilities and infrastructure." Israel was then required to dismantle settlements established after March 2001, freeze all settlement activity, remove its army from Palestinian areas occupied after 28 September 2000, end curfews and ease restrictions on movement of persons and goods. Israeli–Palestinian talks in 2007 and 2008 From December 2006 to mid-September 2008, Israeli Prime Minister Ehud Olmert and President Mahmoud Abbas of the Palestinian Authority met 36 times; there were also lower-level talks. In 2007 Olmert welcomed the Arab League's re-endorsement of the Arab Peace Initiative. In his bid to negotiate a peace accord and establish a Palestinian state, Olmert proposed a plan to the Palestinians. The centerpiece of Olmert's detailed proposal is the suggested permanent border, which would be based on an Israeli withdrawal from most of the West Bank. Olmert proposed annexing at least 6.3% of Palestinian territory, in exchange for 5.8% of Israeli land, with Palestinians receiving alternative land in the Negev, adjacent to the Gaza Strip, as well as territorial link, under Israeli sovereignty, for free passage between Gaza and the West Bank. Israel insisted on retaining an armed presence in the future Palestinian state. Under Abbas's offer, more than 60 percent of settlers would stay in place. Olmert, for his part, was presenting a plan in which the most sparsely populated settlements would be evacuated. Olmert and Abbas both acknowledged that reciprocal relations would be necessary, not hermetic separation. They also acknowledged the need to share a single business ecosystem, while cooperating intensively on water, security, bandwidth, banking, tourism and much more. Regarding Jerusalem the leaders agreed that Jewish neighborhoods should remain under Israeli sovereignty, while Arab neighborhoods would revert to Palestinian sovereignty. The Palestinians asked for clarifications of the territorial land swap since they were unable to ascertain what land his percentages affected, since Israeli and Palestinian calculations of the West Bank differ by several hundred square kilometres. For them, in lieu of such clarifications, Olmert's 6.3–6.8% annexation might work out closer to 8.5%, 4 times the 1.9% limit the Palestinians argued a swap should not exceed. The talks ended with both sides claiming the other side dropped follow-up contacts. Following the conflict that erupted between the two main Palestinian parties, Fatah and Hamas, Hamas took control of the Gaza Strip, splintering the
