By most measures, Africa is safer today than it has been in the modern era: Diseases are less deadly and wars are less frequent. But recent years have also been marked by a rise in radical extremism on the continent, and the terror threat could derail some of the world’s fastest-growing economies.

Dealing with the spread of radicalization has been a central focus of U.S. President Barack Obama’s foreign policy during his time in office.

Few areas have been spared over the past eight years, with much of the continent living in the shadow of a violent extremist group: al-Shabab in Somalia and East Africa, Islamic State (IS) in Libya, al-Qaida in the Islamic Maghreb (AQIM) in Mali, the Lord’s Resistance Army in central Africa, and Boko Haram in Nigeria.

The Obama administration has searched for answers to this problem with varying degrees of success. Obama’s military strategies included aerial bombardment, intelligence assistance, logistical support and training missions.

A militarized foreign policy isn’t what many of the president’s supporters in Africa or at home wanted when he took office, but it is what Obama determined was necessary.

“We’ve seen this terror threat grow, and the administration response has been to ramp up [military-to-military] cooperation to continue and enhance drone strikes so there’s new drone bases in a number of countries on the continent that didn’t exist before the Obama administration,” said Joshua Meservey, policy analyst specializing in Africa and the Middle East at the the Heritage Foundation. “So that’s been a central thrust of his foreign policy. Perhaps, yes, that is a disappointment to some on the continent who were hoping for what is termed as a more equitable relationship.”

‘Military engagement’

In Somalia, the U.S. has offered training to African Union troops fighting the al-Shabab insurgents as well as to Somali National Armed Forces preparing to take over security responsibilities in the fragile country.

In Libya, the U.S. assisted with an aerial campaign in the last quarter of 2016 to degrade the abilities of IS in the city of Sirte and other strongholds. This came several years after the U.S. and NATO allies participated in the ouster of Libyan President Moammar Gadhafi.
In Nigeria, the U.S. has offered intelligence support, equipment, advice and training in the fight against Boko Haram.

In central Africa, 100 U.S. military advisers have been deployed in an unsuccessful search for the warlord Joseph Kony.

“The U.S. has deepened its military engagement with Africa,” said Alex Vines, head of the Africa Program at U.K.-based Chatham House. “Under [former President] George W. Bush there was the launching of the U.S.-Africa Command, a dedicated command focusing on Africa, and so the Obama administration has just really continued that trend.”

Vines said the U.S. model is not to have large bases on the continent, which are costly and unpopular. The strategy is more about finding ways to perform counterterrorism operations that leave a small footprint.

Preferred strategies are those that rely on drone or aerial strikes or those that can be termed force multipliers, such as sharing intelligence and providing training.

Perhaps the most high-profile U.S. military engagement with the continent came during the Ebola outbreak of 2014 when the U.S. sent about 2,800 soldiers, in addition to doctors and aid workers, to build treatment units, treat patients and contain the spread of the virus in Liberia.

“Hundreds of thousands, maybe a couple million lives were saved,” Obama said during his 2016 State of the Union address. “When we help African countries feed their people and care for the sick, it’s the right thing to do, and it prevents the next pandemic from reaching our shores.”
