Hillary Clinton defended on Monday her push for regime change in Libya while she served as secretary of state, telling MSNBC’s Chris Matthews the U.S. “didn’t lose a single person” in the North African country.

But the Democratic presidential candidate appears to have forgotten about the Sept. 11, 2012 terrorist attacks that left dead Ambassador Chris Stevens, State Department information officer Sean Smith and former Navy SEALs Tyrone Woods and Glen Doherty.

Clinton was one of the most ardent voices for invading Libya and deposing its dictator, Col. Moammar Gaddafi. The New York Times recently reported in detail how Clinton helped convince an ambivalent President Obama to enforce a no-fly zone in Libya and to support rebel forces.

Matthews asked Clinton how she could support regime change in Libya while now opposing the 2003 invasion of Iraq.

[dcquiz] “Libya was a different kind of calculation, and we didn’t lose a single person,” she said in defending her apparently conflicting positions.

Two elections have been held in Libya since Gaddafi’s ouster, Clinton pointed out. But she did not acknowledge that ISIS has gained more power in the majority Muslim nation.
