The Iranian-backed militia in Yemen, the Houthis, officially entered the ongoing conflict on Saturday morning local time by firing their first round of ballistic missiles into Israel. This action marks the opening of a new front in a war that began in late February, compounding the conflict involving the United States, Israel, Iran, and Hezbollah in Lebanon.
The intervention by the Houthis adds a new layer of complexity to the region’s hostilities. The escalation is expected to widen the war, spreading the offensive and defensive resources of both American and Israeli forces even further across the Middle East.
Beyond ballistic missiles, the Houthis hold the capability to disrupt maritime traffic through the Red Sea. The militia has warned that its fingers are on the trigger, ready to attack vessels transiting the Bab el-Mandeb Strait off the coast of Yemen, a crucial shipping lane that connects Asia, Africa, and Europe.
Oil tankers and cargo ships traveling from the Indian Ocean rely on the Bab el-Mandeb Strait to access the Red Sea and continue toward the Mediterranean. The waterway facilitates the transit of about 12 percent of global seaborne oil, making it the world’s fourth-busiest shipping choke point and the main route for Saudi Arabia’s oil exports.
Any Houthi attacks on this shipping route would exacerbate the global turmoil already triggered by Iran’s current blockade of the Strait of Hormuz. The Houthis previously refined this battle plan during the Gaza war, where they launched over 100 missile and drone attacks on commercial shipping in the Red Sea and sank at least two cargo ships.
By officially entering the fight, the Houthis intend to inflict greater economic and political pressure on Washington. Furthermore, Yemen serves as a more advantageous geographical base than Iran for launching strikes against Gulf nations that currently host United States military bases and installations.
Should the Houthis expand their missile attacks beyond Israel, it could prompt Gulf states to launch retaliatory offensive strikes. Such an escalation would likely draw the entirety of the Middle East into a more intense and destructive conflict.
US President Donald Trump has repeatedly asserted that the war with Iran will conclude in a matter of weeks. However, the formal entry of the Houthis into the conflict presents a direct challenge to this timeline and threatens to push the region into further chaos.
