As the last US troops depart Niger, a troubling picture emerges – a continent increasingly vulnerable to the spread of extremism, with American eyes now dimmed.

The military drawdown in Africa, driven by recent coups and strained relations, coincides with a critical time: Islamic State (ISIS) and al-Qaeda affiliates are digging in, presenting a potential future threat to the US and its allies.

Numbers on the Rise, Capabilities Unclear

Intelligence gathered from the recently shuttered $100 million drone base in Agadez, Niger, previously provided a crucial window into the activities of extremist groups in West Africa.

General Michael Langley, head of US Africa Command (AFRICOM), acknowledges the challenge, telling reporters from Reuters: “Our ability to monitor the threat is degraded because of the loss of Agadez.

While ISIS numbers in Somalia hover around 200, the much larger al-Shabaab boasts an estimated 10,000-12,000 fighters.

The question haunting military officials is not just their size but their capabilities.

Have they been growing in capability where they can do what we call external ops attacks on the homeland and attacks on allies, whether we’re talking about Europe or anyone?ponders General Langley, highlighting the fear of future assaults on US soil or against allies.

“I’d say it has the potential as they grow in numbers,” he added.
