Obama has conceded that the intervention “didn’t work”.
White House spokesman Josh Earnest on Monday said Obama’s regrets extended to what “the United States and the rest of the members of our coalition didn’t do”.
“The president has tried to apply this lesson in considering the use of military and other circumstances,” Earnest said.
“That asking the question about what situation will prevail and what sort of commitments from the international community will be required after that military intervention has been ordered by the commander in chief.”
In March, Obama made a searing critique of the British prime minister, David Cameron, and the former French leader, Nicolas Sarkozy, for their roles in the bombing campaign they led in Libya.
Cameron had become “distracted” and Sarkozy wanted to promote his country during the 2011 Nato-led military intervention, Obama said in an interview with The Atlantic magazine.
Since the downfall of Gaddafi, who was killed in a popular uprising, Libya descended into near-anarchy – ruled by rival militias vying for power while the Islamic State group has gained influence in the country.
As for the best day in the White House?
“The day that we passed health care reform,” Obama said.
“We sat out on the Truman Balcony with all the staff that had worked so hard on it and I knew what it would mean for the families that I’d met who didn’t have health care.”
The president said his worst day in the White House was when he travelled to Newtown, Connecticut, after a gunman shot 20 young children and six adult staff members at an elementary school in December 2012.
