Greater and Lesser Tunbs
After the UK announced in 1968 that it would end its administrative and military positions in the Persian Gulf, Iran moved to reattach the island politically to the mainland. On 30 November 1971 (two days before the official establishment of UAE), Iran and Sharjah signed a Memorandum of Understanding. They agreed to allow Sharjah to have a local police station and Iran to station troops on the island according to the map attached to the Memorandum of Understanding. The agreement also divided the island's energy resources between the two signatories. "By agreeing to the pact, the tiny emirate prevented an invasion by Iran, which two days earlier had taken two other disputed islands, the Greater and Lesser Tunbs, which were even smaller and uninhabited."
