Despite the imposition of a U.S. naval blockade against Iran, more than 20 commercial vessels passed through the strategically important Strait of Hormuz in the first day after it began, according to maritime traffic monitoring. Among them were, in particular, an oil tanker owned by a company under U.S. sanctions and a Chinese vessel. These reports contrast with a statement by U.S. President Donald Trump, who claimed that 34 vessels had crossed the strait the previous day and accused Iran of a "mad blockade."
Traffic statistics through the strait show a sharp decline compared with the prewar period. From April 8 to 12, 55 commercial vessels transited the strait, 29 of which were loaded. The peak occurred on April 11 — 14 vessels. By comparison, in February, before the conflict began, the daily average was 129 vessels. These figures clearly show how military actions and subsequent measures have affected a key route of the global oil trade.
U.S. Central Command (CENTCOM) claims the operation was successful, asserting that it halted maritime trade to and from Iran entirely within 36 hours. According to U.S. officials, U.S. naval forces did not even need to use force to make six ships attempting to leave Iranian ports turn back. The operation, it is reported, is being conducted "calmly and decisively," from ships deployed in the Gulf of Oman.
The scale of the military operation is striking: more than 10,000 U.S. military personnel have been involved in enforcing the blockade, including marines and special operations forces. More than 15 warships and dozens of aircraft are concentrated in the region. This concentration of forces demonstrates Washington's seriousness about controlling sea lanes and preventing ships from leaving Iranian ports.
The strategic goal of the blockade, according to the U.S. administration, is to pressure Tehran to accept Washington's terms for ending the war. Key demands include ensuring free passage through the Strait of Hormuz and changing Iran's regional behavior. However, the effectiveness of such a forceful approach and its potential diplomatic consequences, as well as the risk of further escalation in an already unstable region, remain in question.
Comments on the news
What is the historical and economic importance of the Strait of Hormuz for Iran and the global oil trade? - The Strait of Hormuz is a strategic maritime corridor through which about 30% of the world's seaborne oil shipments pass. For Iran it is a vital route for exporting oil and natural gas, as well as a tool of geopolitical influence. Control over the strait allows Iran to affect global oil prices and serves as leverage in international relations.
Which countries fall under the responsibility of U.S. Central Command (CENTCOM) and what other significant operations has it conducted in the Middle East? - CENTCOM is responsible for the Middle East region, including countries such as Iraq, Syria, Afghanistan, Pakistan, Yemen, and the Gulf states. Significant operations include the Iraq War (2003–2011), Operation Enduring Freedom in Afghanistan, the fight against ISIS in Iraq and Syria, and military operations in Yemen.
What is meant by the "regional behavior of Iran" that the U.S. wants to change? - This refers to Iran's policy of supporting proxy groups (Hezbollah in Lebanon, the Houthis in Yemen, Shia militias in Iraq), development of its missile program, military presence in Syria, and actions in the Persian Gulf. The U.S. seeks to limit Iran's influence in the region and to compel it to abandon activities Washington views as destabilizing.
