The current Red Sea crisis did not emerge overnight, but followed a decade of escalating Houthi aggression.

The movement's trajectory began with Yemen's seizure, expanded through attacks on Saudi Arabia, and eventually threatened global commerce.

Understanding that progression helps explain why governments increasingly view the Houthis as an international security challenge.

In September 2014, Houthi fighters swept south from Saada and seized Sanaa, forcing Yemen's internationally recognized government from power.

By early 2015, the movement controlled much of northern Yemen through armed conquest rather than elections or a popular mandate.

The Islamic Revolutionary Guard Corps (IRGC) and Hizbullah provided training, weapons and strategic assistance that helped transform the movement's military capabilities.

From Yemen's civil war to regional aggression

The Houthis subsequently launched repeated missile and drone attacks against Saudi cities, airports, energy facilities and border communities.

In June 2019, a Houthi drone struck Abha International Airport's arrivals hall, injuring 26 people, including women and children.

On September 14, 2019, coordinated drones and cruise missiles struck Saudi Aramco facilities at Abqaiq and Khurais, disrupting production.

The attack temporarily removed an estimated 5.7 million barrels of daily production, demonstrating the movement's potential global economic impact.

Houthi violence also inflicted enormous suffering inside Yemen through sieges, arbitrary detention, alleged torture, recruitment of children and attacks.

Officials have documented extensive abuses, while Yemen's broader conflict has produced a catastrophic humanitarian toll over years.

Taiz endured prolonged fighting and siege conditions, while aid workers and civilians faced detention, intimidation and violence under Houthi authorities.

Those actions undermined claims that the movement's military campaign primarily represents Yemen's population or its political aspirations.

Red Sea attacks turn local conflict global

Beginning in November 2023, the Houthis expanded their campaign to international shipping, citing solidarity with Palestinians during the Gaza war.

They attacked commercial vessels with ballistic missiles, cruise missiles, drones and unmanned boats across the Red Sea and Gulf of Aden.

The campaign forced many shipping companies to reroute vessels around Africa, increasing transportation times, insurance costs and pressure on global supply chains.

The Suez Canal subsequently suffered a major decline in revenue as traffic fell amid heightened security concerns and diversions.

The United States and international partners responded by deploying naval forces and conducting strikes against Houthi missile and drone infrastructure.

That response reflected a broader judgment that freedom of navigation cannot depend on whether armed groups approve individual vessels.

Iranian, Hizbullah and other regional support has helped transform the Houthis into an organized criminal militia capable of heavy destruction and violence.

Their arsenal now includes ballistic and cruise missiles, explosive drone boats and other systems extending well beyond traditional insurgent warfare.

The evidence points toward a movement whose capabilities now extend far beyond Yemen's borders and increasingly serve Iranian regional objectives.

Consequently, today's confrontation is not simply another episode in Yemen's civil war, but the culmination of years of escalation.
