Will the United States open a "second front" in the Middle East? Houthi armed group warns: if it intervenes in the conflict, it will face a "heavy blow"

The conflict between Yemen's Houthi armed group and Saudi Arabia is spiraling upward. The Houthis have repeatedly launched ballistic missiles and drones at the Saudi capital Riyadh and military bases, and attacks on Riyadh International Airport and Saudi oil facilities have caused serious casualties and property losses, forcing many international airlines to suspend flights to Riyadh. Facing repeated heavy blows on its own territory and a stretched defense system, Saudi Arabia has urgently asked the United States for help, requesting direct military intervention. The Houthis have publicly warned that if the United States participates in "aggression against Yemen," it will "deal heavy blows to all U.S. interests in the region." At the same time, Saudi Arabia's request has put U.S. President Trump, who is under pressure from the midterm elections, in a dilemma: if he resumes bombing the Houthis, it will not only further push up global energy prices, but also risk dragging the United States into a second Middle East quagmire after the Iran war; if he continues to stand by, it could shake the foundation of the U.S.-Saudi alliance. As Riyadh vows a "serious response," the regional situation may slide toward the edge of a more dangerous cliff.
