Not so: Olmert got along well with the Palestinian Authority of the West Bank, as shown by the Annapolis Conference of 2007:
"A joint understanding, read by US president George Bush, stated that "In furtherance of the goal of two states, Israel and Palestine, living side by side in peace and security" the parties agreed to"immediately launch good-faith bilateral negotiations in order to conclude a peace treaty, resolving all outstanding issues, including all core issues without exception, as specified in previous agreements". A steering committee would meet from 12 December 2007, followed by biweekly negotiations between President Abbas and Prime Minister Olmert.
"The parties also committed to immediately implement their respective obligations under the Roadmap for peace and to continue the implementation of it until they had reached a peace treaty, to be concluded before the end of 2008."

It was Hamas (primarily in Gaza) that responded to peace overtures with unremitting violence. That was when Olmert targeted their leadership.
oralloy: " Likud did not take power until Benjamin Netanyahu was elected in 2009."
As noted above, Likud was in power under Netanyahu until the Barak government was formed in July 1999; Barak's coalition was powerless in the Knesset and collapsed in December 2000. Sharon of Likud formed a new government in March 2001. Though nominally a coalition government, Likud with PM Sharon's help dominated, and the Labor Party pulled out in 2002. The new government under Sharon was a Likud dominated coalition with other right wing parties. When in 2004 Sharon decided on disengagement including withdrawal of settlements in Gaza, his right wing coalition allies deserted him. He brought Labor back in then started his own party, Kadima.
As noted above, when Olmert took over his government made excellent and quick progress with the Palestinians of Fatah; it was Hamas that became the spoiler.
Hamas was culpable, not Olmert. But when Netanyahu and Likud retook power, Likud and Hamas became jointly culpable for pursuing the joint policy of no peace settlement and no Palestinian state.
