The Feb. 19 airstrike on an apparent Islamic State (IS) training camp near Sabratha isn’t the precursor to a sustained American air campaign in Libya, US officials have made clear.

Instead, the pre-dawn bombing that killed some 40 suspected terrorists near the border with Tunisia appears to be better understood as a one-off operation aimed at protecting that fledgling democracy from militants who would plunge it into chaos. Pentagon spokesman Peter Cook said the strike aimed to take out Tunisian national Noureddine Chouchane, a prime suspect in the 2015 attacks that killed 60 people in Tunis and Sousse, along with a camp where foreign fighters were training for possible “external attacks on US interests in the region.”

“I think this [attack] should be treated separately than the Libya issue,” said Christopher Chivvis, the associate director of the International Security and Defense Policy Center at the Rand Corporation. “I think this has much more to do with Tunisia than it does with Libya.”

The “isolated compound” that was destroyed by F-15 jets and unmanned aircraft, he said, is “nothing like going after the thousands of [IS] fighters” present in their Libyan stronghold of Sirte, hundreds of miles to the east.
