The Houthis Aren’t Done — Are We?

The US Navy spent over $1 billion and suffered an additional $100 million in equipment losses and damages during Operation Rough Rider, countering the Houthi threat in the Red Sea. Yet Iran’s Yemeni proxy remains heavily armed and prepared to resume its attacks. 

Over the past two years, the Houthis continued to fire their extensive stockpile of Iranian missiles and drones at Israel and maritime targets despite repeated US and Israeli airstrikes against them. As the Houthi threat to regional security and Red Sea trade persists, the United States can work with Israel to prepare for any potential future operations if the Houthis resume attacks by expediting the sale of necessary military equipment to Israeli forces, and collaborating with Israel to improve intelligence on critical Houthi targets to neutralize.

Protecting global freedom of navigation through international waterways, safeguarding maritime trade, and supporting Israel’s security remain core US interests. Yet, the Iranian-armed and funded Houthi terrorist group has compromised these interests over the past two years by firing hundreds of drones and missiles at both Israel and ships transiting the Red Sea.

The Houthis’ violent assault on US Navy and commercial shipping assets in the region prompted several rounds of US airstrikes, including Operation Rough Rider, which resulted in US forces carrying out over 1,100 strikes against the group’s infrastructure in early 2025. However, since the May 6 agreement between the Houthis and the US — which bans Houthi attacks against American ships but does not prohibit targeting other commercial vessels or Israel — the terrorist group has fired over 150 projectiles at Israel and ships transiting the Red Sea, including several that injured Israeli civilians and sunk two commercial vessels.

While these attacks prompted retaliatory Israeli strikes on the terror group, including one operation that killed several Houthi senior leaders in August, the Iranian proxy remained undeterred and fired nearly 50 projectiles in September alone.

The current pause in Houthi attacks is not the time to rest; instead, the United States and Israel should strengthen their readiness for future operations against the enduring threat that the well-armed Houthis pose to regional stability, security, and maritime trade. With Iran continuing to strengthen its proxy during this pause by funneling it more weapons to replace those it has fired or lost, the United States should work with Israel to prevent this arms proliferation and prepare for any potential offensive operations against the Houthis if they resume their regional assault. 

To start, US and Israeli forces should take advantage of the current ceasefire to refine their intelligence gathering and counter-terror strategies, particularly by establishing a comprehensive list of Houthi targets in case of resumed attacks. Before the Houthis began firing at ships and targeting Israel, countering their activities was not a priority for the US or Israeli militaries and intelligence agencies. The limited effectiveness of these airstrikes further exposed this lack of focus. The Houthis’ persistent ability to launch attacks throughout the war, coupled with Iran’s ongoing proliferation of advanced weaponry, underscores critical intelligence gaps that both the United States and Israel must address to anticipate and effectively prepare for future military operations.

For example, Israel’s operations in the fall of 2024 against Hezbollah, and Operation Rising Lion against Iran’s nuclear and military targets, vividly illustrated a military campaign’s effectiveness when leadership prioritizes planning and intelligence preparation during peacetime. Unlike the situations in Gaza or against the Houthis, Israel spent years meticulously preparing for large-scale operations in Lebanon and Iran, and this preparation enabled it to achieve rapid and decisive results. To position US and Israeli forces for similar levels of success, it remains crucial for both to collaborate on acquiring intelligence for targets while the Yemen front remains quiet.

With Israeli aircraft needing to fly thousands of miles to conduct strikes in Yemen — even further than the distance to Iran — the United States would improve Israeli operations in both countries by expediting the delivery of KC-46 aerial refueling aircraft to Israel. These advanced aircraft have better range, refueling capacity, and defensive capabilities than Israel’s current fleet of over 50-year-old Ram tankers, based on Boeing 707s. Israel is currently set to receive the first of four KC-46 aircraft it has purchased by the end of 2026 and requested two more in August, but expediting the sale and delivery of these refuelers would position Israel’s forces to sooner carry out more effective counter-terror operations if the Houthis resume attacks. In addition, the United States should begin training Israeli pilots immediately on how to operate these aircraft, ensuring they are ready to carry out any future missions in Yemen once the new refuelers arrive.

The United States and Israel must remain vigilant, despite the relative calm. With the Houthis still a capable threat to regional stability, now is the time to prepare for any future conflict with Iran’s Yemeni proxy.
