The US military deployed more than 10,000 personnel and over a dozen warships to enforce the blockade.

In the first 24 hours, six merchant vessels complied with orders to turn around.

A US-sanctioned Chinese tanker transited the strait, raising questions about enforcement.

The blockade covers all of Iran's approximately 1,500-kilometer coastline.

Enforcement Challenges

Enforcing the blockade presents significant operational challenges given the volume of shipping traffic.

International law requires humanitarian aid to be allowed through.

The blockade is selective and does not stop all shipping, creating a gray zone in enforcement.

Iran retains a powerful advantage due to the geography of the strait.
