Pete Hegseth announces indefinite US naval blockade to curb Iran's aggression

US Defense Secretary Pete Hegseth said on Tuesday that Washington can keep a naval blockade of Iran “indefinitely,” a statement that signals the United States is prepared to maintain a military presence in the Persian Gulf and surrounding waters for the long term. Hegseth made the comment during a briefing in Washington, after the US Navy intensified its patrols around key shipping lanes following a series of Iranian attacks on commercial vessels. The blockade is aimed at limiting Iran’s ability to export oil and to curb its missile and drone programs, which the US and its allies say threaten regional stability.

The blockade matters because the Gulf is a vital artery for global trade. Roughly 20 % of the world’s oil passes through the Strait of Hormuz, a narrow waterway that Iran controls. In recent months, Iran has fired missiles at shipping in the Gulf and threatened to close the strait in retaliation for US sanctions. Washington’s decision to keep a permanent naval presence is a direct response to those threats and to the broader dispute over Iran’s nuclear program. The US has repeatedly warned that any Iranian use of ballistic missiles or drones against civilian targets would trigger a military response.

Hegseth’s remarks come amid rising tensions in the region. The US has already deployed more than 30 warships to the area, and the Pentagon has increased surveillance of Iranian naval activity. Allies in the Gulf, including Saudi Arabia and the United Arab Emirates, have welcomed the move, saying it protects their shipping and counters Iranian influence. Iran has denied that it intends to close the Gulf and has called the blockade an act of aggression. The US says it will continue to engage diplomatically, but it is also prepared to use force if Iranian forces attack US or allied vessels.

Looking ahead, the US is likely to keep its naval forces in place for months or years, depending on diplomatic negotiations and the security environment. The blockade could keep Iranian oil exports down, affecting global oil prices and the economies of oil‑dependent countries. It also raises the risk of a broader conflict if Iranian forces target US or allied ships. Meanwhile, the US and Iran have been in talks to restart nuclear negotiations, but progress has stalled. The international community will watch closely to see whether the blockade forces Iran to negotiate or pushes it toward further isolation.
