Though some believe the war on terror winds down with the US departure from Afghanistan, the threat it was supposed to address burns fiercely on my continent. Africa is the new frontline of global militancy. Yet few expect the outlay expended here to be as great as in Afghanistan. The fight against terrorism begun under the George W Bush administration was never truly global.

Despite rising attacks across Africa in the past decade, international assistance has not followed in step. Mozambique is merely the latest African state in danger from terrorism. The Sahel remains vulnerable to Boko Haram, 20 years after its formation, and other radical groups. Somalia is in its second decade fighting the equally extreme al-Shabaab. Many African nations are submerged under the weight of insurgency.
