Houthi Advance Threatens Bab al-Mandab and Global Shipping
Yemen has been fighting a civil war for many years.
The Houthis control Yemen’s capital and large parts of the north and west.
They recently moved quickly along the Red Sea coast and captured important locations.
One of those locations is near Bab al-Mandab, a narrow waterway used by many ships carrying fuel and other goods.
If ships cannot safely use the waterway, they may have to take a much longer route around Africa.
This could raise transportation costs and affect energy supplies.
Saudi-backed forces are trying to push the Houthis back.
The United States must decide whether to become more involved, even though earlier air campaigns did not defeat the Houthis.
The fighting is also testing a new defense agreement involving Saudi Arabia, Pakistan, and Turkey.
Houthi forces captured Mocha and reached Perim Island during a rapid southward offensive along Yemen’s Red Sea coast.
The Bab al-Mandab Strait, a narrow gateway to the Red Sea and Suez Canal, carries about 7% of global petroleum supplies.
Saudi-backed Yemeni forces are trying to recover territory, while the United States has offered intelligence support but declined direct intervention.
The advance could give Iran-aligned forces influence over both Bab al-Mandab and the Strait of Hormuz, increasing pressure on energy and shipping routes.
The Houthi attacks are also testing whether the Saudi Arabia–Pakistan–Turkey Mecca Joint Defence Agreement creates real military obligations.

Intervention advocates
Intervention skeptics
United States military involvement
Intervention advocates
The United States may need to act because Houthi control or disruption of Bab al-Mandab threatens freedom of navigation, energy supplies, and American security commitments.
Intervention skeptics
A new campaign could consume aircraft, ships, intelligence resources, and air-defense munitions, while previous Saudi-led and American strikes failed to defeat the Houthis.
Meaning of the Mecca defence agreement
Intervention advocates
The agreement’s collective-defense principle could require Pakistan and Turkey to provide practical assistance such as intelligence, air defense, naval support, weapons, or forces.
Intervention skeptics
The partners have different security priorities, and Pakistan has said that no military response under the agreement has been discussed, suggesting it may remain mainly diplomatic.

- The Houthis control Sana’a and much of northern and western Yemen.
- Recent territorial gains

- Bab al-Mandab width
- The strait is about 29 kilometers wide at its narrowest point.
