In the wake of the British decision to end its protectorate agreements in the Persian Gulf, Iran took decisive military action to assert its control over the Greater and Lesser Tunbs, islands that had long been a point of contention between different regional powers. The operation involved the rapid deployment of Iranian forces, who faced little opposition from the local Emirates, Sharjah and Ras Al Khaimah, which were unable to mount a significant defense. The seizing of these islands was characterized by swift air and naval operations, showcasing Iran's military capabilities under the rule of Shah Mohammad Reza Pahlavi.

Geographically situated at the entrance to the Strait of Hormuz, the Greater and Lesser Tunbs are of strategic importance for oil shipping lanes and military positioning. With this move, Iran aimed to solidify its influence in the region, especially in the context of the geopolitical shifts occurring as the British military presence diminished. The aftermath of the operation saw Iran solidifying its control over the islands while the smaller emirates grappled with the implications of Iran's assertiveness.

The actions surrounding the seizure of the islands not only set the stage for future regional tensions, but they also highlighted the emergence of Iran as a dominant power in the Persian Gulf. The event had significant ramifications for the local emirates and their security strategies, leading to shifts in alliances and interactions with larger global powers, particularly as the region was poised for turmoil due to the upcoming Iranian Revolution and oil crises.
