Kadima leader Tzipi Livni on Sunday asserted that she was the only leading candidate who was capable of forming a broad national unity government if elected. "I believe that after the elections I will be the only one who can offer a national unity government that includes Netanyahu and Barak on each side, because we are in the center," Livni told high school students in Jerusalem. "A centrist party is not a vacuum; some kind of gap between the Left and the Right. Being centrist means promoting the goals and interests of the State of Israel as a Jewish and democratic state and simultaneously promoting political and security processes," the foreign minister said. "We need to advance peace with the moderate elements and then we can hit Hamas and enlist the world to prevent a nuclear Iran." Livni went on to say that Iran was "not only Israel's problem" and expressed confidence that the "free world" understood the nature of the threat from the Islamic Republic.
