The UAE joins the Saudi-led military intervention in Yemen
On 26 March 2015 the United Arab Emirates joined Operation Decisive Storm, the Saudi-led air-and-later-ground intervention in Yemen against the Houthi movement. In the causal graph this event strengthens Forced-Displacement Scale, a driver that strengthens People Internally Displaced by Conflict and Violence (IDMC) — a worsening welfare path.
Read the full account
On 26 March 2015 the United Arab Emirates joined Operation Decisive Storm, the Saudi-led air-and-later-ground intervention in Yemen against the Houthi movement. Mohamed bin Zayed was crown prince and deputy supreme commander.
Context
Saudi Arabia led. The UAE contributed aircraft and later ground forces, then backed southern groups. He was the security principal, not yet president. He did not write a UN Security Council resolution. Later drawdowns are neighbouring later instruments.
Later STC support and 2022 Yemen council meetings are neighbouring files. The Qatar blockade is 2017.
The president of the United Arab Emirates is elected by the Federal Supreme Council of the seven emirates and is, in this case, also Ruler of Abu Dhabi and supreme commander of the armed forces. He does not write UNFCCC consensus texts by himself, IAEA operating licences, Israeli Knesset statutes, or UN panel reports.
Why it matters
The path is humanitarian access and forced displacement: a completed intervention in Yemen produced civilian harm, blockade effects, and southern fragmentation. It is not a unique UAE homicide count.

What the sources establish
Emirates News Agency carries the official instrument or communique. Reuters records the same dated act independently.
Established: a 26 March 2015 UAE entry into the Saudi-led Yemen intervention, independently reported.
Not established: a unique later Yemeni death coefficient as his personal count, or that the Houthis never fired.
Saudi Arabia led. Yemeni parties fought. The UN did not order the campaign.. A later repeal, court stay, or successor order would be a different Fact with a different date. That pair identifies The UAE joins the Saudi-led military intervention in Yemen, not a later speech about The UAE joins the Saudi-led military intervention in Yemen.
Co-authors and later implementers named in Context remain on the file. If a later repeal, stay, or successor decree exists, it needs its own date and its own row. The contribution described on this Person row is limited to He was deputy supreme commander and Abu Dhabi’s security principal. Saudi Arabia led. Yemeni parties fought. The UN did not order the campaign. That limit is the alternative to treating office-holding as authorship of every later series.
