Thomas Kelly, the American ambassador here, likes to say that Djibouti today feels like what Casablanca must have felt like in 1940. “All the different nationalities elbowing into each other,” he says. “All the intrigue.” ... About 4,000 soldiers and contractors live here, and they include commandos from Joint Special Operations Command, the team that undertakes the military’s most sensitive counterterrorism operations. After the 2012 attack on the diplomatic mission in Benghazi, Libya, a 150-member rapid response team was established at Camp Lemonnier, assigned to handle future threats to diplomatic personnel abroad. Djibouti is also the U.S. military’s regional hub for drones, and it sends thousands of Predators and Reapers across the region each year.
