The mandate cannot be set before the membership

Saudi Arabia is trying to build an international coalition to protect shipping in the Red Sea from Houthi attacks. Al Jazeera reported that deliberations with dozens of countries continue and that the composition of the coalition has not yet been finalised. The order matters here: who is to be protected, in which waters, and with what authority to use force cannot be written down before it is settled who carries that protection.[1]

Leaving the membership open may not be an oversight; it may be the bargain itself. The list of participating states also fixes what the coalition is authorised to do; a broad list tends to produce a narrow mandate and a narrow list a broad one. A more superficial explanation is also available: this may be the ordinary sequence of preparation seen before any alliance announcement.[1]

Two different requests on the same calls

Saudi Foreign Minister Prince Faisal bin Farhan received calls from his counterparts in Qatar, Kuwait and Bahrain and, as reported, those calls stressed the importance of continuing efforts to de-escalate tensions. The Houthis announced a maritime blockade of Saudi Arabia on 20 July, citing what they called a nearly 12-year siege of Yemen; Riyadh struck facilities at Hodeidah port.[1]

On one side of the scale sits the military arrangement Riyadh wants to build; on the other, its neighbours' publicly stated preference. The two do not exclude each other, and neither substitutes for the other. The language of de-escalation and a decision to join a protection force do not amount to the same commitment. A state asking for de-escalation has not thereby committed forces to a patrol.[1]

The moment an invitation becomes a commitment

Whether this effort becomes a coalition will be settled by the publication of a joint text. If within two months a founding statement appears that names the participating states and sets out the task, the invitation stage will have closed. If no such text appears, what exists is a running invitation list, and the protection of shipping in the Red Sea stays with the separate decisions of individual states.[1]
