U.S. oil blockade may not topple Iran and could even reinforce the regime

The current U.S. approach, articulated by the Trump administration, seeks to extend a naval blockade that curtails Iran’s oil exports, aiming to pressure Tehran as cease-fire negotiations remain at an impasse. However, a decline in oil revenue does not automatically weaken authoritarian rule; nations such as Azerbaijan, Angola and Equatorial Guinea have endured decades of reduced oil income while retaining power. The crucial factor is the degree to which regime-supporting institutions rely on oil money; when that reliance wanes, leaders draw on other sources of loyalty—nationalism, military victories, or ethnic patronage—to stay in control.

Iran’s government, already engaged in conflict with the United States and Israel and hit by sanctions and infrastructure attacks, has so far withstood economic pressure without collapsing. Continued attacks could actually boost nationalist fervor and tighten elite and security-force allegiance, undermining the goal of prompting defections. Consequently, analysts advise Washington to pursue targeted diplomatic measures aimed at specific Iranian concessions, judging success by behavioral change rather than by the depth of economic hardship.
