Conservative News DailyApril 16, 2026

U.S. military leaders announced an active blockade of Iran’s ports and coastline, stating that ships headed to or from Iranian ports will face interdiction and perhaps the use of force if they do not comply. Gen. Dan caine said the blockade is active, applies to all ships regardless of nationality, and will be enforced inside Iran’s territorial seas as well as in international waters. So far, 13 ships bound for Iran have turned around. The briefing suggested the United States could transition quickly from blockade operations to major combat operations if needed, with warnings to vessels in the Indo-Pacific region and beyond. Secretary of War Pete Hegseth echoed the sentiment of readiness for a rapid, more forceful response. The report also mentions efforts to counter iran’s oil shipments via dark fleet networks and notes social-media posts and other official commentary accompanying the declaration.

Ships that are on a mission to support Iran will face the full military might of the United States, Chairman of the Joint Chiefs Gen. Dan Caine said Thursday.

During a briefing, Caine said the blockade is an active operation, not a passive one.

“Let me be clear: This blockade applies to ALL ships, regardless of nationality, heading into or from Iranian ports,” Caine said in a video posted to X.

“The U.S. action is a blockade of Iran’s ports and coastline, not a blockade of the Strait of Hormuz. Enforcement will occur inside Iran’s territorial seas and in international waters,” he said.

“In addition to this blockade, the joint force, through operations and activities in other areas of responsibility, like the Pacific area of responsibility … will actively pursue any Iranian-flagged vessel or any vessel attempting to provide material support to Iran. This includes dark fleet vessels carrying Iranian oil,” he said.

Caine said that to date, 13 ships heading for Iran have turned around, according to The Hill.

“The captains of all these ships made the wise decision not to move transit or run this blockade,” Caine said. “So far, 13 ships have made the wise choice of turning around.”

“As we continue to hold this blockade at the order of the Secretary and the President, any vessel that fails to comply with our instructions will be dealt with accordingly,” Caine said.

Caine said that ships in the Indo-Pacific Command area of responsibility “that left that area before we began the blockade” could also be stopped.

Caine said vessels are warned “do not attempt to breach the blockade. Vessels will be boarded for interdiction and seizure, transiting to or from Iranian ports, turn around or prepare to be boarded. If you do not comply with this blockade, we will use force.”

“If you do not comply with the blockade, we will use force,” Caine said.

During the briefing, Secretary of War Pete Hegseth said U.S. forces can quickly “make the transition” from the blockade to “major combat operations,” according to CBS News.

“We can make that transition again very quickly and even more powerfully than ever,” Hegseth said.

At Pentagon briefing, Hegseth invokes the Bible to say “our press are just like the Pharisees” and calls coverage of war “unpatriotic.”

“At the direction of President Trump, the War Department will ensure that Iran never has a nuclear weapon, never. We prefer to do it the nice way through a deal led by our great vice president and negotiating team, or we can do it the hard way,” he said.
