Washington is recasting its stalled confrontation with Iran as an economic offensive, threatening not only Tehran but any country that helps keep its economy running. The strategy promises maximum pressure—but risks turning Iran’s crisis into a wider confrontation with China and other trading partners.

Treasury Secretary Scott Bessent has branded the campaign an “economic D-Day,” presenting secondary sanctions as the next decisive phase after months of military pressure. The administration says it has targeted nearly 60 firms, individuals and vessels tied to Iran’s oil, nuclear, missile and cyber networks, while warning that “no one is above the reach of U.S. sanctions.”¹

The conservative case is that economic isolation can finish what military action began. Bessent says Washington intends to “sever Iran’s economic lifelines” and impose consequences on countries that sustain them.² In this framing, sanctions are not merely punitive; they are a campaign to force Tehran into strategic surrender.

The liberal and critical view is more skeptical. The United States has yet to achieve its stated military or diplomatic objectives, and the proposed sanctions remain partly a threat rather than an implemented policy. One analysis described the move as an attempt to accomplish through “economic strangulation what military force has so far failed to achieve,” while warning that sanctions are unlikely to produce a quick settlement favorable to Washington.³

China is the central test. Beijing is Iran’s largest trading partner and rejects pressure as a solution, arguing that the dispute should be handled through diplomacy.³ Yet Bessent says Chinese entities that help turn Iranian oil “into money, into repression” will be targeted.⁴ Tehran, meanwhile, has threatened retaliation through land, sea, air or cyber operations.³

The result is a campaign whose language suggests finality but whose consequences remain uncertain: Washington seeks capitulation, while Iran and China appear prepared to test how far the United States will go.
