Barack Obama

The terror organization's rise in a tumultuous Middle East has provided Obama some of the toughest decisions of his presidency, choices that CNN's Fareed Zakaria explores in "The Legacy of Barack Obama" airing Wednesday.

"The ability of ISIL to not just mass inside of Syria, but then to initiate major land offensives that took Mosul, for example, that was not on my intelligence radar screen," Obama told Zakaria, using the administration's term for the Islamic State terror group.

The 100-page document highlights areas where the US falls short and calls on the private sector to help hasten the improvement of digital services.

President Barack Obama set up the commission in preparation for the new administration.

He said its recommendations should be followed within the first 100 days of Mr Trump's presidency.

By convention, former presidents tend to leave the political fray and avoid commenting on their successors.

Mr Obama said he would give Mr Trump time to outline his vision but added that, as a private citizen, he might speak out on certain issues.

Mr Trump spent the weekend interviewing candidates for top jobs in his cabinet.

"I want to be respectful of the office and give the president-elect an opportunity to put forward his platform and his arguments without somebody popping off," Mr Obama said at a forum in Lima, Peru.

Instead, Obama found himself warning of an impending shift in the global order, one he advised could lead to a "meaner, harsher, more troubled world" if not stopped.

"Whoever is president and whoever is the chancellor of Germany and whoever is the leader of other European nations and other democracies around the world, they need to recognize that," Obama said. "There are going to be forces that argue for cynicism. For looking the other way with somebody else's problems. That are not going to champion people who are vulnerable because sometimes that's politically convenient."

Obama said this during a news conference on his final overseas trip that the President-elect had tapped into a "troubling" strain of rhetoric playing on Americans' fears of globalization to win the presidency.

Speaking in Athens, Obama said he recognized an "anger and fear in the American population" over threats of mechanization and globalization, but that Republican officials didn't use facts when making their case about the US economy.

But in his first news conference since last week's stunning election results, Obama warned that some of Trump's expectations will soon be shaken up by the gravity of the job.

Obama said he was certain after meeting Trump last week that his successor and longtime political foe was "sincere" about being president for all Americans but also called on the President-elect to reach out to people who felt anxious after the explosive rhetoric of the campaign, including women and minorities.

Xiao Jiguo, a 30-year-old Chinese actor, rose to fame for his uncanny resemblance to the outgoing president.

Such is Mr Xiao's fame in his homeland, that the direction and popularity of US foreign policy had direct impact on his own burgeoning career.

"People in media, television programmes and movies were worried that inviting me could become political."

"When President Obama holds office, I sort of have to take political factors into account. But after he steps down, my path as an actor may become clearer," Mr Xiao told the BBC.

Trump said he was 'looking forward to dealing with the president in the future', while Obama claimed he was 'very encouraged by the interest in President-elect Trump to work with my team'.

But even to the untrained eye it was clear there was some tension, and body language expert Patti Wood has analyzed the first meeting between the most powerful man in America and the person chosen to replace him.

Obama was 'extremely fatigued, resigned and not hopeful', while Trump was 'tentative, serious and perhaps fearful', Wood told DailyMail.com.

The first lady hosted the soon-to-be first lady for tea and a tour of the White House residence, Press Secretary Josh Earnest said in the White House briefing.

A photo released by the White House showed the two sitting next to each other in gold chairs speaking in the Yellow Oval Room, located in the residence of the White House.

Earnest said during the visit to Trump's future home, the two moms discussed raising children in the White House.

Three days after mocking Trump as unfit to control the codes needed to launch nuclear weapons, Obama told his successor that he wanted him to succeed and would do everything he could to ensure a smooth transition.

Trump, who spent years pursuing Obama over false claims he is not a natural-born American and accused him of being the founder of ISIS on the campaign trail, called Obama a "very good man" and said he would seek his counsel in future.
