The United States has officially handed over its last military base in Niger, Airbase 201 in Agadez, to the ruling military junta, marking the completion of a withdrawal process that began in March. This move follows the junta's decision to terminate the agreement allowing U.S. troops to operate in the country, with American forces now required to leave by September 15. The withdrawal has significant implications for U.S. counterterrorism efforts in the Sahel region, which has seen rising threats from groups linked to al-Qaeda and the Islamic State. Despite the U.S. having invested heavily in military assistance in Niger, the junta has turned towards Russia for security support. Remaining American personnel are primarily focused on administrative duties as the full withdrawal unfolds. The situation has raised concerns among critics about the potential security vacuum in the region.
