So, if most Israelis actually back the removal of settlements (and polls have suggested similar results for decades), why have colonies simply expanded so much for so long? Talk is cheap, actions are what matter. And on the ground, Israeli Jews are complicit in the occupation and have been since 1967 (if not before):
A survey of the Israeli general public and Israeli settlers taken in early March shows three-fifths of the Israeli public (60%) support “dismantling most of the settlements in the territories as part of a peace agreement with the Palestinians.” This is eleven points higher than the previous reading (49%) taken in December, 2009, and is the highest level recorded since 2005, during the debate over evacuating the Gaza Strip. Just one-third of the Israeli public (33%) opposes dismantling most settlements, including 13 percent very strongly opposed. This is the lowest level of strong opposition to dismantling settlements recorded by the Truman Institute for the 26 surveys in which this question has been asked since 2001.
In contrast to the views of the Israeli public, among Israeli settlers a large majority (69%) oppose dismantling most West Bank settlements. Moreover, a majority of settlers believe most of the Israeli general public shares its opposition to dismantling settlements.
