Former President Bill Clinton acknowledges he got "very close" to helping achieve peace in the Middle East shortly before ending his eight years in office.
Over a two-week period in 2000, Clinton played host at Camp David to then-Israeli Prime Minister Ehud Barak and Palestinian Authority Chairman Yasser Arafat.
The summit ultimately ended without agreement. Two U.S. presidents later, the conflict rages on.
Now, Clinton is less optimistic Middle East negotiators will get that close again, telling CNN that peace between Israel and the Palestinians is impossible until Hamas renounces violence.
"There is no way the Israelis are going to give up the West Bank and agree to a state unless Hamas agrees to give up violence and recognizes Israel's right to exist," he said in the interview airing Monday on "New Day."
When islanders first got a glimpse of Jose Salvador Alvarenga, they saw an extremely weak man wearing only tattered underwear.
On his battered boat, a live bird was tethered by its foot - narrowly missing becoming his next meal.
And as he recounted his story, faster than his rescuers could comprehend, Alvarenga ate like he hadn't had a full meal in months.
As crazy as it sounds, his tale just might be true after all.
New details from the day Alvarenga mysteriously turned up in the Marshall Islands appear to lend weight to his story of drifting across the Pacific Ocean for 13 months.
It was a rainy, windy day on Ebon, the atoll where Alvarenga was found January 30.
Mayor Ione deBrum was first alerted to the mysterious visitor when a boy biked to her office from the other side of the island. The boy had been dispatched by Amy Libokmeto and Russell Laikedrik - the islanders who first spotted Alvarenga, yelling and waving a knife from one island over.
Libokmeto motioned for him to drop the knife, and then the pair sprang into action, sending word to the mayor and providing Alvarenga with food, water and clean clothes, deBrum told CNN.
Alvarenga inhaled pancake after pancake as he and his rescuers communicated with each other using a mix of charades and hand-drawn pictures. DeBrum's son even helped translate the Salvadoran's story, using Spanish skills learned entirely from the animated children's series "Dora the Explorer."
The story was beyond belief for many.
Alvarenga said he set off in late 2012 from Mexico on what was supposed to be a one-day fishing expedition. But he and a teenage companion were blown off-course by northerly winds and then caught in a storm, eventually losing the use of their engines. They had no radio signal to report their plight, he said.
Alvarenga said that four weeks into their drift, his companion died of starvation because he refused to eat raw birds and turtles. Eventually, he threw the body overboard.
Alvarenga's claims have garnered widespread skepticism about how he could survive the more than 6,000-mile trek across the open ocean. But officials in the Marshall Islands have said repeatedly they have no reason to doubt the story.
After more than a week on the island, Alvarenga began his journey home Monday.
Plans for his repatriation to El Salvador were postponed last week after his health took a turn for the worse. But Marshall Islands Foreign Minister Phillip Muller said Monday that the castaway was in good health and ready to travel.
Alvarenga later boarded a flight that took off for Hawaii.
The flight from Amata Kabua International Airport is expected to arrive in Honolulu at 7.55 a.m. ET.
On Tuesday, Alvarenga is expected to eventually arrive in El Salvador.
It's been more than six years since Madeleine McCann vanished while on holiday with her parents in Portugal.
But neither her parents nor the detectives investigating her case are giving up on one day finding the little girl from Leicestershire, England.
Her disappearance is set to get renewed attention Monday when investigators make another appeal to the public on BBC's "Crimewatch," releasing two computer-generated sketches of a man spotted around the resort town of Praia da Luz on the day then-3-year-old Madeleine went missing. The sketches are based on descriptions from two separate witnesses.
Retired FBI Supervisory Special Agent Stephen Moore weighs in on this new development saying the original investigators "did the classic mistake. They decided on a conclusion very early on. They screwed it up from the beginning and now it has to be returned."

"Today I am asking the public for their help. Whilst this man may or may not be the key to unlocking this investigation, tracing and speaking to him is of vital importance to us," Detective Chief Inspector Andy Redwood said in a statement Monday before the program, which will air in the United Kingdom, the Netherlands and Germany. "We have witnesses placing him in the resort area around the time of Madeleine's disappearance."
The man is described as white, between 20 and 40 years old, with short brown hair and a medium build.
