Nearly six months after President Donald Trump vowed a swift victory over Iran, the conflict appears to be at a standstill, with prospects of a military victory or negotiated settlement growing dimmer.
To break the deadlock, Trump has pledged an “economic D‑Day” under which any country that does business with Iran would face “tremendous” economic consequences.
Iran, however, has long faced sanctions and has shown a willingness to endure pain, and a capacity to adapt to immense economic and military pressure as the conflict drags on.
The key question for the U.S. now is whether further sanctions will work where other strategies have failed.
The exact mechanics of the new U.S. economic pressure campaign remain unclear, with Treasury Secretary Scot Bessent promising to reveal them in a news conference on 24 August.
In a CNBC interview, Bessent was clear: the U.S. was willing to apply pressure to any country‑friend or foe that helps Iran, saying, “You’re either with us or against us. If you insist on doing business with Iran, the Treasury will enforce against you.”
Vice‑President JD Vance called the sanctions the “new phase” of the conflict, arguing that economic pressure is the most effective tool available to the U.S. He said, “We’re going to keep that going because we think that’s the best way to ultimately achieve the final objective.”
Iran has faced significant U.S. sanctions since the Islamic Republic’s inception in 1979, intensified after the Trump administration withdrew from the Joint Comprehensive Plan of Action in 2015.
Alongside Operation Economic Fury—a two‑pronged U.S. economic campaign combining Treasury‑coordinated sanctions against regime finances and a naval blockade of Iranian ports—Trump’s new strategy aims to expand the sanctions blast radius by targeting third‑country firms that still trade with Iran.
Geostrategy expert Imran Bayoumi, former defense policy adviser, told the BBC that April’s announcement is a manifestation of mounting frustration that other options have not delivered Trump’s desired results. He said, “This is simply another tool; the broader question of strategy is still unanswered.”
Michael Parker, an eight‑year veteran of the Office of Foreign Assets Control, said that the new strategy will likely push secondary sanctions against firms that touch the U.S. dollar to provide goodness, but notes that the tactic’s success depends on other countries complying, a point he said is “unexplored”.
Parker pointed to foreign banks that help Iran evade sanctions or fund its coffers, saying Iran “finds new roads around it” whenever new names pop up.
The impact of these sanctions will largely hinge on how the target countries—potentially including U.S. allies such as Turkey, Iraq and China—react. Parker noted that Iran’s ability to sidestep sanctions is largely contingent on the willingness of other nations to give it access to the formal banking system.
Some experts question whether ally countries will agree to such pressure, noting that many have navigated their own interests with the Trump administration, and that Iran’s success will depend on the global willingness to enforce these rules.
