When President Trump announced on Truth Social that the U.S. Navy would blockade “any and all Ships trying to enter, or leave, the Strait of Hormuz,” he also instructed the Navy to interdict vessels that had paid tolls to Iran and to destroy mines Iran had placed in the waterway.
CENTCOM subsequently clarified the actual scope: the blockade applies to vessels entering or departing Iranian ports and coastal areas and does not affect ships transiting the strait to and from non-Iranian ports. The blockade is therefore a naval embargo on Iranian trade, not a closure of the strait to international shipping generally.
Trump took the action in response to Iran’s “world extortion.” The IRGC had imposed a de facto toll regime in the strait. The Tehran regime said that vessels would be required to submit documentation, obtain clearance codes, and accept IRGC-escorted passage through a single controlled corridor. Trump’s goal was to stop Iran from policing the strait and profiting from its closure while the rest of the world absorbed the economic damage.
Neither the U.S. nor Israel is dependent on oil transiting the Strait of Hormuz. Around the globe, the U.S. is the primary enforcer of the United Nations Convention on the Law of the Sea (UNCLOS), maintaining freedom of navigation for all countries. Trump’s request for Europe and other allies to support U.S. freedom-of-navigation patrols in the Strait of Hormuz was rejected.
Europe’s argument was that the U.S. took action against Iran unilaterally and therefore could not expect European support. President Trump’s position is that the U.S. has spent trillions defending Europe and keeping sea lanes open around the globe for 70 years, and it was reasonable to ask for reciprocity.
Instead, Europe blames Trump for the Hormuz closure, completely ignoring the fact that it is the IRGC, not the U.S., that has closed the strait.
Their refusal to help reopen it is a classic example of cutting off your nose to spite your face, since Europe’s energy supplies are at stake, not America’s. However, anger at Trump is mobilizing Europe to form a coalition to protect the Strait from America rather than from Iran.
