President Joe Biden and Western allies will not be able to halt Yemen-based Houthi attacks on international shipping in the Red Sea, according to a top White House official.

“This needs to be an all-hands-on-deck effort,” White House national security adviser Jake Sullivan told the World Economic Forum in Davos, Switzerland. “And so, we want to work with countries across the board — countries who are allies and partners, countries who are not — in the common interest to get this to stop.”
