Operation Decisive Storm Operation Decisive Storm was a 2015 air campaign led by Saudi Arabia and the United Arab Emirates with allied Arab states against Houthi and allied forces in Yemen. The operation followed the 2011 Yemeni revolution and the Yemeni Crisis (2011–present), aimed at restoring Abdrabbuh Mansur Hadi to power and countering perceived influence from Iran. It drew immediate international attention, involving regional powers, United Nations envoys, and humanitarian organizations.
Background
The operation grew from the 2014–2015 advance of the Houthi insurgency from Saada Governorate toward Sana'a, culminating in the seizure of the Yemeni capital and the resignation of Prime Minister Khaled Bahah. Negotiations during the National Dialogue Conference (Yemen) failed to prevent escalation, while the ousting of President Abdrabbuh Mansur Hadi prompted the Hadi government to seek external assistance from Gulf Cooperation Council. Concerns about Iran–Saudi Arabia proxy conflict and the strategic importance of the Bab-el-Mandeb strait, alongside incidents like the Battle of Aden (2015) and attacks on Hadi administration assets, led to a coalition formation. Preceding operations and international crises such as the Arab Spring and the Syrian Civil War contextualized regional alignments.
Belligerents and Commanders
The coalition was spearheaded by Saudi Arabia and the United Arab Emirates, with contributions from Bahrain, Kuwait, Qatar, Egypt, Jordan, Morocco, and Sudan; political leadership included figures like Salman of Saudi Arabia and Mohammed bin Zayed Al Nahyan. Operational commanders included senior officers from the Royal Saudi Air Force and the United Arab Emirates Air Force. Opposing forces comprised the Houthi leadership under Abdul-Malik al-Houthi and forces loyal to former President Ali Abdullah Saleh, with military elements from the Yemen Armed Forces and tribal coalitions. International actors such as United States advisors, the United Kingdom, and France provided intelligence, logistics, and arms sales, linking to broader networks including NATO-partner cooperation and bilateral defense ties.
Course of Operations
The campaign began on 26 March 2015 with intensive air strikes targeting Sana'a International Airport, military bases, and Houthi-controlled facilities, using platforms associated with Panavia Tornado, Boeing F-15E Strike Eagle, and multirole aircraft. Ground and naval components included two-week naval blockade measures around the Red Sea approaches and interdiction near the Gulf of Aden. Notable engagements occurred during the Battle of Aden (2015), sieges of Taiz and Al Hudaydah, and clashes around the Bab-el-Mandeb corridor. The coalition declared a shift to a new phase, citing degraded Houthi air defenses and targeted strikes against command-and-control nodes. Amid operations, incidents such as the bombing of civilian infrastructure and contested strikes on Sana'a University-adjacent areas provoked global scrutiny. Parallel diplomatic moves included UN Special Envoy to Yemen mediation attempts, ceasefire proposals, and the eventual transition of the campaign into another designated phase as international pressure mounted.
International Response and Diplomacy
The operation prompted statements from the United Nations Security Council, debates within the European Union, and reactions from regional actors including Iran, which vocally opposed the campaign. Key diplomatic efforts involved envoys like Ismail Ould Cheikh Ahmed and later Sergio Vieira de Mello-era institutional precedents; the UN Security Council Resolution 2216 (2015) and successive resolutions framed sanctions and political demands. Countries such as United States, United Kingdom, and France offered varying levels of logistical support, while non-aligned states voiced concerns at forums including the Organisation of Islamic Cooperation and Arab League. International organizations—International Committee of the Red Cross, Médecins Sans Frontières, and United Nations High Commissioner for Refugees—called for access and ceasefires. Bilateral relations between Saudi Arabia and Iran deteriorated, and allied coordination involved entities like the Gulf Cooperation Council and the Arab Coalition command structures.
Humanitarian Impact and Casualties
Air strikes, blockades, and ground fighting caused significant civilian displacement, infrastructure damage, and disruptions to healthcare and food supplies. Humanitarian agencies including World Food Programme and United Nations Children's Fund reported acute shortages, while outbreaks of disease such as cholera followed the collapse of services. Casualty figures remained contested among Amnesty International, Human Rights Watch, and coalition statements, with reports of civilian deaths in Sana'a, Aden, Taiz, and Al Hudaydah. Port restrictions affected deliveries to Al Hudaydah Governorate, exacerbating famine risk as tracked by Integrated Food Security Phase Classification. Displacement engendered refugee flows toward Djibouti and Somalia as documented by United Nations High Commissioner for Refugees.
Legal and Political Aftermath
The campaign raised questions under International humanitarian law and sparked investigations and reports by organizations such as Amnesty International and Human Rights Watch alleging potential violations including indiscriminate attacks and impediments to aid. Debates within national legislatures—such as the House of Commons of the United Kingdom and the United States Congress—examined arms sales and legal responsibilities. The operation contributed to shifting alliances, the eventual assassination of Ali Abdullah Saleh-aligned figures, and the later Yemeni peace process attempts mediated by the United Nations. Long-term political consequences included strengthened Houthis resilience, regional strategic recalibrations among Saudi Arabia, United Arab Emirates, and Iran, and continued international litigation and accountability initiatives pursued by NGOs and UN panels.
