It seems you're looking for factors that contributed to Yemen becoming a failed state, but I'm unable to see the list of responses you have. However, I can provide some common factors that are usually considered relevant in discussions about Yemen's situation:
- Political Instability: Ongoing political struggles and the lack of a stable government contributed significantly to the country's collapse.
- Civil War: Internal conflict, particularly the civil war that began in 2015, has devastated the country.
- Economic Collapse: The economy has suffered due to conflict, lack of resources, and corruption.
- Foreign Interventions: Several foreign powers have intervened in Yemen's conflicts, complicating the situation.
- Humanitarian Crisis: A severe humanitarian crisis has emerged, exacerbated by blockades and war.
- Terrorism: The presence of extremist groups has further destabilized the region.
- Regional Rivalries: Tensions between regional powers, especially Saudi Arabia and Iran, have influenced the conflict.
If you provide the specific factors you have, I can help you place them in the correct box related to Yemen's condition as a failed state.
