In the recent years Chad, Guinea, Mali and Sudan caught the international attention for which one of the following reasons common to all of them?

Answer: D. Chad, Guinea, Mali and Sudan caught international attention due to SUCCESSFUL COUPS. All four African countries experienced military coups during 2021-2023: - CHAD: April 2021, Mahamat Idriss Deby took over after his father President Idriss Deby was killed by rebels. - GUINEA: September 2021, Colonel Mamady Doumbouya overthrew President Alpha Conde. - MALI: August 2020 (Colonel Assimi Goita against President Keita) followed by a second coup in May 2021. - SUDAN: October 2021, General Abdel Fattah al-Burhan overthrew the civilian transitional government. Later in April 2023 conflict erupted between the army (SAF) and Rapid Support Forces (RSF), creating a full civil war. This wave of military takeovers (sometimes called the 'African coup belt') prompted concern from ECOWAS, African Union and UN about democratic backsliding and Russia/Wagner influence. Distractors fail: (A) Rare earth discoveries are not a common 2021-23 feature for all four. (B) Chinese military bases are concentrated at Djibouti, not these four. (C) Sahara expansion is gradual; not a 'caught attention' event. Source: African Union / ECOWAS communiques / Council on Foreign Relations conflict tracker.
