The long-dormant conflict over Western Sahara has resurged in recent years, challenging regional stability. Diplomatic tensions between the main sides, coupled with the collapse of the 1991 UN-brokered cease-fire and US recognition of Moroccan sovereignty in 2020, have complicated the situation. The appointment of UN envoy Staffan de Mistura in 2021 offers hope for the revival of cease-fire talks, while the UN and the United States aim to stabilize the conflict through renewed diplomatic efforts.
