Iran vows a devastating military response to new US threats to bring down its leadership through economic sanctions. Major-General Ali Abdollahi, chief of staff of Iran's armed forces, states Iran's reaction would be broad and decisive, responding with crushing, punishing and devastating responses across land, sea, air, air defense, and cyberspace. Iranian Parliament Speaker Mohammad Bagher Ghalibaf calls the planned US sanctions unjust and urges Iran to plan to overcome them. Ghalibaf, the main negotiator in mediated talks with the United States, accuses the US and Israel of resorting to economic and cognitive warfare after failing in direct military confrontation. US Treasury Secretary Scott Bessent announced on August 20 that the United States will impose the toughest sanctions in history on Iran, with details expected on August 24. President Donald Trump warned on August 19 of tremendous Economic Consequences against any country providing any type of lifeline to Iran. Bessent called on allies to choose sides, stating the plan aims to collapse this regime. He also suggested that maximum economic pressure would likely prevent a large-scale kinetic restart of military force. China rejects the US demand to join the sanctions campaign. A spokesperson for the Chinese Embassy in Washington states that sanctions and pressure do not help resolve the problem and calls for political and diplomatic solutions. Chinese Foreign Ministry spokesman Lin Jian reiterated this position on August 21. Iranian Foreign Minister Abbas Araghchi dismissed the US threats as economic terrorism and a diversion from America's own crisis: unprecedented debt and surging interest costs. Oil prices steadied on August 21 but were on track for a second weekly rise, having hit a more than three-week high on August 20 following the sanctions threat. The conflict has killed thousands of people, drawn in Gulf nations, and affected shipping through the Strait of Hormuz, which carried about a fifth of all traded oil before February. US officials report over 750 US military members injured and 18 killed since the Iran war began. China purchased more than 80% of Iran's shipped crude in 2025.

Where they split

  • Some international outlets, such as RT (Russia Today) and The Independent, frame the US actions as "economic terrorism" or "economic D-Day" directly in their headlines, reflecting Iranian official statements.
  • US major sources like The New York Times and Reuters focus more on the statements from Iranian officials regarding overcoming sanctions, rather than Iran's military response.
  • Several independent and international sources, including Al-Monitor and Daily Sabah, provide specific details about the US naval blockade and its imposition in April, which is less emphasized in some US major coverage.
  • Some articles, like The Independent, include details about US military casualties (757 injured, 18 killed) since the Iran war began, a detail not present in all other coverage.
