1971 Abu Musa Sharjah Iran MOU
A point that often gets lost in the Abu Musa debate is that you do not actually need to resolve the sovereignty question to understand why the UAE has a serious grievance with Iran.
In 1971, Sharjah and Iran reached a very specific arrangement over Abu Musa. Neither side gave up its sovereignty claim. Instead, they agreed to divide practical jurisdiction: Iranian troops could occupy a clearly defined area, and Iran would have full jurisdiction there. Sharjah would retain
full jurisdiction over the remainder of the island, with its police, administration and civilian population continuing under Sharjah's authority.
That is important because Iran's initial arrival on Abu Musa was therefore not simply an unrestricted annexation. Iranian forces entered a
pre-determined portion of the island while the remainder remained under Sharjah's civil administration.
The UAE's grievance is that Iran later appears to have gone well beyond those agreed limits.
The clearest turning point was
1992. Iranian authorities began preventing some non-UAE nationals employed by the UAE from entering the Sharjah-administered area and imposed passport/visa requirements, effectively treating access to the whole island as entry into Iranian territory.
That cuts directly across the central bargain of the MOU:
Iranian jurisdiction in the agreed Iranian area; Sharjah jurisdiction over the rest.
The UAE subsequently protested further Iranian activities and infrastructure, including an airfield and other facilities, as part of a broader expansion of Iranian administration beyond the territory allocated to it under the 1971 arrangement.
There is an important nuance here. Iran issued a separate statement in 1971 reserving the right to take measures it considered necessary for the security of the island.
But
that reservation was not itself part of the mutually agreed MOU. It was an Iranian unilateral declaration. Sharjah did not amend the MOU to say that Iran could exercise unrestricted security or governmental jurisdiction over the entire island.
That distinction matters.
A unilateral statement by one party cannot simply rewrite the agreed text, particularly when the agreed text expressly says that Sharjah retains
full jurisdiction over the remainder of Abu Musa.
So even if Iran believed it had wider security rights, that is different from saying Sharjah contractually accepted those rights.
The grievance can therefore be stated without taking any position on ultimate sovereignty:
Sharjah allowed Iran onto Abu Musa under an agreement that expressly limited Iranian jurisdiction to a designated part of the island. Iran subsequently began exercising governmental control beyond that area and increasingly treated the entire island as Iranian territory.
That creates an obvious tension in Iran's position. If Iran relies on the 1971 arrangement to argue that its original military presence on Abu Musa was consensual, then the same agreement also contains the limitation on where Iranian jurisdiction was supposed to apply.
In other words, the UAE case is not merely:
"We say Abu Musa belongs to us."
There is a separate and arguably cleaner complaint:
"Whatever the final sovereignty question, Iran agreed in 1971 to a defined division of jurisdiction and subsequently stopped respecting it."
The sovereignty dispute can remain unresolved while that grievance remains perfectly coherent.
