Barack Obama was elected president some 143 years after the abolition of slavery in the United States. As teary-eyed African-Americans watched Obama's 2008 election night speech in Chicago's Grant Park, none could have imagined that America's first black president would leave his own legacy of slavery — in Africa.

However, that's exactly what he did, thanks to a combination of imperial hubris, disregard for constitutional restraints on executive war powers, and the use of false pretenses.

In 2011, egged on by Secretary of State Hillary Clinton and a handful of other advisors, Obama ordered a months-long series of air strikes that facilitated a NATO-backed regime change campaign that toppled Libyan leader Muammar Gaddafi.

Rather than ushering in liberal democracy and prosperity, the ouster of Gaddafi left the country fractured, with two rival governments and various militias vying for power. Obama's regime change marked the start of an ongoing era of chaos, with some of the greatest resulting evils inflicted on black Africans.
