Former Israeli President Shimon Peres left office only a week ago, yet it's already clear that his influence in the Israeli public sphere - and perhaps beyond - will remain significant.
He spoke with Wolf Blitzer on Thursday about the current conflict in Gaza, and how to go about finding a lasting peace between Israelis and Palestinians.
"I cannot see a cease-fire with rockets and with tunnels," Peres said. "Only a cease-fire without rockets and without tunnels."
Peres does not view Hamas as the legitimate political rulers of Gaza, referencing Hamas' coup of the territory in 2007.
He believes Gaza should be controlled by the Palestinian Authority, the ruling entity of the West Bank, and its president, Mahmoud Abbas.
"I don't think that two countries can bring peace," Peres said of a divided West Bank and Gaza. "Two countries will continue war."
Peres regards Abbas, or Abu Mazen, as he is known to Palestinians, as an essential figure in achieving Israel-Palestinian peace.
"He got the courage, more than any other Arab leader, to stand up and say, 'I'm against terror. I'm against kidnapping ... I'm for peace,'" Peres said.
