The peace agreements were broken too many times. The peace agreements included a promise by Israel to desist colonizing Palestinian land. Under Ehud Barak, new illegal settlements were built in the Occupied Territories and thousands of Israelis moved into them.

Ariel Sharon OTOH is a mad dog. If he was building the Apartheid Wall along the internationally recognized border (green line) instead of using it to steal half the West Bank and 70% of its water, the Wall would not have been challenged in the courts.
The wall is the best idea of the century. The Wall is the most short-sighted idea this century. It will force Palestinians resisting the occupation to professionalize and attack Israelis throughout the world like the Armenian Secret Army's war on the Turks last century.
