Videos of men and women being sold in Libya have led experts to question the role the Obama administration played in the North African country's instability six years after the president ordered an intervention there.

Obama has called the aftermath of the 2011 intervention, when Libyan leader Muammar Gaddafi was overthrown, the "worst mistake" of his presidency—and some experts agree.

"The responsibility is on Barack Obama's administration," Alan J. Kuperman, associate professor at the University of Texas at Austin, told Newsweek. "He made the decision to overthrow Gaddafi."

Human rights violations—including the Libyan slave trade revealed in a CNN investigation—are a result of U.S. interference, according to some experts.

CNN released a video of migrants being sold for about $400 in an auction, though there have been accounts of slaves being sold for as little as $200.
