The Persian Gulf is an important strategic region for the grand strategy of the United States and its position as a great power. The Persian Gulf region has traditionally been at the heart of US interests because it is one of the most important oil producing regions in the world. GCC countries are important military partners for the United States, and military and security agreements, arms sales, and capacity building are essential elements of US engagement with GCC partners. This article examines the strategic priorities of the United States and the security role of this actor in the field of security in the Persian Gulf, as well as the type of security and military relations between the GCC and the United States. The main question of this research is whether the distinctive US strategies have increased the stability of the Persian Gulf or whether these strategies have been largely irrelevant? This study, using the qualitative method and the type of documentary, US security trends that have been developed to protect the region are analyzed, which includes offshore and territorial balances. The dominant hypothesis of this paper is the resurgence of the offshore balance as a new US strategy for the security of the Persian Gulf, because it seems that due to the existing constraints and challenges, this change is more appropriate for Washington's overall strategy. The findings of the study indicate that there is no clear evidence that US security commitments in the Persian Gulf are critical to regional stability.
