Israel's then prime minister Ariel Sharon began a policy of disengagement from the Gaza Strip in 2003. This policy was fully implemented in August 2005. Sharon's announcement to disengage from Gaza came as a tremendous shock to his critics both on the left and on the right. A year previously, he had commented that the fate of the most far-flung settlements in Gaza, Netzararem and Kfar Darom, was regarded in the same light as that of Tel Aviv. The formal announcements to evacuate seventeen Gaza settlements and another four in the West Bank in February 2004 represented the first reversal for the settler movement since 1968, dividing Sharon's party. It was strongly supported by Trade and Industry Minister Ehud Olmert and Tzipi Livni, the Minister for Immigration and Absorption, but Foreign Minister Silvan Shalom and Finance Minister Benjamin Netanyahu strongly condemned it. It was also uncertain at the time whether this was simply the beginning of further evacuation.
