More U.S. Troops Arrive in Middle East

The Wall Street Journal's What's News podcast recaps Monday's key developments centered on the escalating Iran war, including new US troop deployments in the Middle East, alongside Pakistan's mediation bid, Europe's scramble for gas alternatives, ongoing US airport disruptions, and select business deals.

US Troops Bolster Options Against Iran

A new unit of over 2,000 US troops—the 31st Marine Expeditionary Unit, comprising about 2,200 Marines and sailors from three warships—has arrived in the Middle East. Described as the military's "Swiss Army knife," the unit expands President Trump's options amid the war's intensification over the weekend. Potential roles include raiding or seizing Tehran-militarized islands in the Strait of Hormuz, which Iran has effectively shut down; capturing Karg Island, the launch point for 90% of Iran's oil exports; escorting ships through the strait; or seizing Iranian oil tankers, akin to past Venezuela operations. It could also serve as deception to distract Iran during other missions, such as seizing nearly 1,000 pounds of uranium to hinder nuclear weapon development—a complex operation not yet approved. White House Press Secretary Caroline Levitt emphasized the Pentagon provides options without implying decisions, while US Central Command declined comment.
