Labor MK Isaac Herzog on Sunday praised President Shimon Peres's calls to negotiate with PA President Mahmoud Abbas, calls that were strongly condemned by the Likud party."President Peres expresses in a decisive and clear manner the need for action, and not just declarations and talking, in the diplomatic field," Hertzog said."The Netanyahu-Liberman government has led us to new heights of international isolation and stagnation that risks the future of the state of Israel as a Jewish state," he added.
