Which country is identified as a regional rival of Iran in its foreign policy?

• A. United States
• B. United Kingdom
• C. Israel
• D. Saudi Arabia

Answer: (D)

The idea being tested is identifying Iran’s main regional rival in its foreign policy. Saudi Arabia fits that role because the two powers compete for influence across the Middle East and the Gulf, driven by sectarian (Shia Iran vs. Sunni Saudi Arabia) and ideological differences. This rivalry plays out in proxy conflicts and regional alignments, such as Iran supporting Assad in Syria and various Shiite groups, while Saudi Arabia leads coalitions against Houthi forces in Yemen and backs opposition blocs in other theaters. These ongoing clash points shape Iran’s regional strategy and priorities, making Saudi Arabia the clearest regional rival.

The United States is a major external power with adversarial moments, but it isn’t a neighboring regional rival in the way Saudi Arabia is described in Iran’s regional strategy. The United Kingdom and Israel are also important actors, but Saudi Arabia is the most direct, persistent regional competitor in Iran’s foreign policy narrative.
