"What Paris Taught Us About The Islamic State" (Clint Watts, War on the Rocks)
"Al Shabaab's violent path in Somalia over the past few years is instructive of what we currently see with the Islamic State. By 2010, al Shabaab had reached its peak before a containment strategy slowly shrunk its harshly enforced sharia state and pushed it out of key urban strongholds. As the group retracted, its strategy and operations shifted from conventional fighting and insurgency to terrorist attacks, first in Somali cities like Mogadishu before expanding regionally throughout the group's support network and support base in the Horn of Africa. Today, al Shabaab holds a fraction of the territory it once dominated, but continues to launch fierce terrorist attacks against soft targets. The lesson is this: If an extremist group that has seized territory starts to lose it, it will be highly incentivized to turn to terrorist operations that allow for maximizing effects at a lower cost. The Islamic State propelled its recruitment and resourcing over the past three years by sustaining the initiative, growing its state through battlefield successes and acquisitions. But the group has now peaked: It is losing territory, many of its fighters are dying in battle, defections from their ranks continue to increase, recruitment flows are slower and smaller, and new regional Islamic State affiliates in countries like Libya and Egypt now provide a range of options for potential recruits to join a group locally rather than travel to Syria."
