In 1980, the UAE took its claim to the United Nations,[23] but the claim was deferred by the UN Security Council at that time and it was not revisited.[1][5] According to author Thomas Mattair, executive director of Middle East Policy Council (MEPC), given that Iran has consistently refused to consider mediation or arbitration from third-party groups such as the ICJ, Mattair considers the invasion a violation of Article 33 of the United Nations Charter.[24] Iran has continues to reject all claims to the islands, describing them as an inseparable part of Iranian territory.
Intransigent, intractable Iran, in a world of diplomacy, which intransigence is fitting in many cases, but when the owner is a mafia....
Now is the time for the UAE to get back those islands with U.S. help, and Prez Trump is undoubtedly happy to oblige. I sure do hope that the plan is to take Kharg Island, and facilitate the return of the 2 strategically located islands in the Gulf to the UAE which will also give us a base for operations.
Iran invasion under Shah Pahlavi was given pass because Iran had obviously a lot bigger military.
Iran was also considered a stable and reliable country then, so Iran control of these island was considered preferable than that of the Emirates, who were then considered rather unstable and not reliable.
Things change quickly!
