On the 11-12 January, US and UK aircraft and warships conducted at least 70 strikes on multiple military targets in Houthi-controlled Yemen. Reports indicate that over 100 precision guided munitions were fired on at least 16 Houthi locations. This includes a military base adjacent to Sanaa airport, a military site near Taiz airport, a Houthi naval base in Hodeidah and military sites in Hajjah governorate. Houthi’s stated that five of the group’s fighters were killed in the strikes with six others wounded.

The Houthi Movement is an Iranian aligned group that controls much of Yemen after nearly a decade of civil war against a Western-backed and Saudi-led coalition. The two sides are currently observing a tentative ceasefire that officially ended in late 2022 but has remained in place to the current day.

Following the outbreak of the Hamas-Israel conflict, the Houthi’s emerged as a strong supporter of the Palestinian Islamist group. The Houthis began attacks on shipping between the Gulf of Aden and the Red Sea in December 2023, claiming to target vessels linked to Israeli persons, businesses, and interests.

However, this route, which links Europe and Asia and Africa via the Suez Canal, accounts for roughly 15 percent of the world’s shipping traffic. The attacks have forced some shipping companies to limit transits through the waterway, or even cease operations altogether, instead taking the longer route around southern Africa. This has significantly disrupted international commerce, increasing delivery costs and time, stoking fears about a global inflation.

In response to the Houthi attacks, the US launched Operation Prosperity Guardian alongside several allies, which aimed to end the blockade and counter all threats by Houthi forces against international maritime trade. The operation was defensive in nature, destroying only missiles launched at vessels with no pro-active strikes conducted. The Houthis continued to fire at merchant vessels, as well as allied naval vessels, dismissing warnings from Washington and London. Then on 9 January, US and British warships shot down 21 drones and missiles, repelling the largest Houthi attack so far.

It is highly likely that the Houthi’s largest attack to date on 9 January was the trigger that surpassed the US-UK threshold. While international prices have yet to see a significant impact, Operation Prosperity Guardian was not working as a deterrent. It is highly likely that more extensive, continued Houthi action would force more merchant vessels away from the Red Sea, almost certainly disrupting maritime trade, therefore increasing consumer prices and shortages.

In the immediate aftermath, the Houthi’s are highly likely to increase their attacks on commercial and military vessels in the region in retaliation. However, it is likely that their ability to launch missiles and drones has been degraded. Should the Houthis sustain their attacks, it is almost certain that the US and UK will continue their strikes on targets within Yemen. It is also highly likely that the group will be re-designated as a terrorist organisation if they continue. This would have a significant impact on the peace process to end the Yemeni Civil War between the Houthi’s and the Saudi-led coalition, which has continued to progress despite regional tensions.

A breakdown of the process would almost certainly see a resumption of hostilities between the two sides, with locations within Saudi Arabia and the United Arab Emirates likely becoming viable targets for the Houthi’s as evidenced by their previous attacks.

Across the Middle East, it is highly likely that Houthi’s allies and other Iranian proxies start to act in solidarity with the group. These groups will almost certainly view the attacks as Western support for Israel.

It is almost certain that Popular Mobilisation Forces (PMF) in Iraq and Syria will continue to target US military bases across the region. It is also likely that the frequency and scale of these attacks will increase considerably. There is a realistic possibility that US military locations that have not been targeted yet in Kuwait, Saudi Arabia, and the UAE, are targeted.

Hezbollah will likely continue to focus its attacks on Israel, however an attack on the US cannot be ruled out. While still unlikely, the US and UK strikes on Yemen have increased the likelihood of a wider conflict developing in the Middle East, as well as the West entering a proxy war with Iran. This eventuality would highly likely take focus away from the conflict in Gaza, almost certainly intensifying the humanitarian situation.
