Houthis Just Joined the War: Iran's Proxy Opens Southern Front

TL;DR

Yemen's Houthis fired two missiles at Israel, opening a southern front that stretches air defenses and threatens Red Sea shipping lanes.

Key Points

• 1.Houthis entered the conflict citing continued military escalation. Their exact justification was "targeting of infrastructure and crimes against brothers in Lebanon, Iran, Iraq, and Palestine"; both missiles fired at Israel were intercepted, but their involvement forces Saudi Arabia, UAE, and Israel to defend against strikes from two opposite directions simultaneously.
• 2.The Bab-el-Mandeb Strait is now the critical new chokepoint. With the Strait of Hormuz already effectively closed by Iran, the Houthis could shut down the second major global shipping pinch point; they previously demonstrated this capability during Operation Rough Rider, forcing a major US naval response.
• 3.Saudi Arabia's bypass pipeline to Yanbu is now a soft target. Built specifically to route oil west and avoid the Iranian blockade at Hormuz, the pipeline runs the entire width of Saudi Arabia and is now potentially vulnerable to Houthi attack.
• 4.Iran's leadership reportedly believes it is winning the war. Israeli security officials told analyst Nadav Ayal that Iran is demanding removal of all US bases and collecting tolls at Hormuz — not as posturing but from genuine belief in their superiority — making them less incentivized to negotiate.
• 5.The 31st Marine Expeditionary Unit of ~3,500 sailors and Marines has arrived in theater. Aboard the America-class amphibious assault ship Tripoli, they are the first large force capable of seizing islands, boarding tankers, or establishing a beachhead — though still far too small for a large-scale Iran invasion.
• 6.The Pentagon is considering sending an additional 10,000 ground troops, potentially reaching 17,000 total. Per the Wall Street Journal, these would include infantry, armored vehicles, and logistical support — a dramatic shift from weeks ago when politicians universally ruled out boots on the ground, with Secretary Rubio still insisting it isn't necessary.
