The Iran War Just Got Bigger — And More Dangerous
Four weeks into Operation Epic Fury, the U.S.-Israeli military campaign against Iran has entered a new and more volatile phase. On Saturday, March 28, Yemen’s Iran-backed Houthi rebels launched their first confirmed missile attack on Israel since the conflict began — a move that dramatically widens an already sprawling regional war.
At the same time, thousands of U.S. Marines have arrived in the Middle East aboard the amphibious assault ship USS Tripoli, Israel has struck Iran’s nuclear infrastructure including the Arak heavy water reactor, and 12 American service members were wounded in an Iranian missile and drone attack on a base in Saudi Arabia.
Here’s everything you need to know about the latest developments.
Houthis Enter the War With Missile Strike on Israel
Yemen’s Houthi rebels confirmed Saturday that they had carried out their “first military operation” in support of Iran, launching a ballistic missile toward Israel. The Israeli Defense Forces detected the missile launch from Yemen and said their aerial defense systems successfully intercepted the threat. No casualties were reported in Israel.
But the significance of this attack goes far beyond the immediate damage — or lack thereof. The Houthis control much of Yemen and have proven themselves capable of sustained missile and drone operations. During the Red Sea crisis in 2024, they disrupted global shipping for months. Their entry into this war signals that Iran’s network of regional proxies is now fully activating.
“This is exactly what military planners feared,” one senior defense analyst told CNN. “The war is no longer contained to Iran. It’s becoming a true regional conflict.”
The Houthis’ involvement also threatens to further rattle already jittery global energy markets. Oil prices have been volatile since the war began on February 28, and any Houthi action in the Red Sea or against shipping lanes would add another layer of disruption to an already strained global economy.
USS Tripoli Arrives With 5,000 Troops
The USS Tripoli (LHA-7), one of the U.S. Navy’s massive amphibious assault ships, arrived in the Middle East on Friday carrying approximately 2,500 Marines from the 31st Marine Expeditionary Unit along with 2,500 American sailors. The ship had been previously stationed near Japan before being redirected to the conflict zone.
The deployment is part of a broader buildup. According to The Wall Street Journal, the Pentagon is now considering sending up to 10,000 additional U.S. troops to the region — on top of the tens of thousands already deployed for Operation Epic Fury.
The 31st MEU is a rapid-response force trained for a wide range of operations, from amphibious assaults to humanitarian assistance. Their arrival near the Strait of Hormuz — where Iran has been attacking commercial shipping and harassing vessels — significantly bolsters American capability in the area.
Since the war began, more than 300 U.S. service members have been wounded in Iranian attacks across the region. The Pentagon has not released a comprehensive casualty update in several days, raising concerns among lawmakers about transparency.
12 Americans Wounded in Saudi Base Attack
In one of the most significant attacks on American forces this week, Iranian missiles and drones struck Prince Sultan Air Base in Saudi Arabia on Friday, wounding 12 U.S. service members. Two were reported in serious condition.
At least one KC-135 air refueling aircraft was hit and caught fire during the attack, according to a senior U.S. official. The loss of tanker aircraft is particularly concerning, as they are critical to sustaining the round-the-clock air operations over Iran.
Iran has been striking back at coalition bases across the Gulf region since the war began. Saudi Arabia, Bahrain, Kuwait, and the UAE have all been targeted with ballistic missiles and drones. On Saturday alone, the UAE intercepted 20 ballistic missiles and 37 drones, bringing its total interceptions since the start of the conflict to 398 ballistic missiles, 15 cruise missiles, and hundreds of drones.
Abu Dhabi reported that falling debris from intercepted missiles caused fires in the Khalifa Economic Zones area, injuring five people.
Israel Strikes Iran’s Nuclear Infrastructure
In a major escalation on the nuclear front, the Israeli Air Force conducted strikes on March 27 targeting key components of Iran’s nuclear program. More than 50 IAF fighter jets participated in the operation, hitting targets across three areas in Iran.
The strikes hit the Arak Heavy Water Production Facility — long considered one of the most sensitive sites in Iran’s nuclear program — as well as the Ardakan Yellowcake Production Plant in Yazd province and sites involved in uranium enrichment.
The IDF stated: “The strikes on these sites and facilities constitute a combined degradation to the regime’s production capabilities, both in its ballistic missile program and its nuclear weapons program. The IDF continues to operate against the regime’s military industries in order to degrade the production capabilities it has built over many years.”
This comes as Reuters reported that Iranian hardliners have intensified calls to develop a nuclear weapon in response to the ongoing bombardment — a scenario that U.S. and Israeli officials had hoped to prevent through the very strikes now being carried out.
Rubio Says War Will End in ‘Weeks, Not Months’
Secretary of State Marco Rubio struck an optimistic tone on Friday after meeting with G7 foreign ministers in France, declaring that the U.S. expects the operation in Iran to conclude in “weeks, not months” and arguing that American forces are “already ahead of schedule.”
But the facts on the ground tell a more complicated story. Reuters reported that the U.S. can only confirm that about one-third of Iran’s missile arsenal has been destroyed. Iran continues to launch daily volleys of missiles and drones at Israel and Gulf state targets, even as the rate of fire has declined from the early days of the war.
Iran has also rejected the 15-point U.S. proposal delivered via Pakistan, which demanded that Tehran dismantle its nuclear program, end uranium enrichment, hand over its enriched uranium stockpile, grant full IAEA access, limit missile capabilities, cease support for proxy militias, and ensure freedom of navigation through the Strait of Hormuz.
Iranian officials called the demands “tantamount to unconditional surrender” and said they would not negotiate under fire.
The Humanitarian Cost
The Iranian Red Crescent has reported at least 1,900 people killed in attacks on Iran since February 28. Iran’s foreign minister previously stated that “hundreds of Iranian civilians,” including more than 200 children, have been killed — figures that have not been independently verified but have drawn growing international concern.
The conflict has also displaced over a million people in Lebanon, where Israel has been conducting strikes against Hezbollah targets as part of the broader campaign against Iran’s proxy network.
What Comes Next
As Operation Epic Fury enters its fifth week, several key questions loom:
Will the Houthis sustain attacks? Their entry into the war could force the U.S. to divert military resources to Yemen, stretching an already massive operation even thinner.
Can Iran keep fighting? Its missile launch rates have declined, and the combined U.S.-Israeli strikes have degraded significant military infrastructure. But Iran’s ability to strike back — as the Saudi base attack showed — remains real.
Will diplomacy get a chance? With Iran rejecting the U.S. proposal and both sides escalating, the window for a negotiated end seems to be narrowing rather than opening.
What about the nuclear question? The strikes on Arak and other nuclear sites may have set back Iran’s program, but reports of hardliners pushing for a weapon suggest the long-term consequences could be the opposite of what Washington intended.
One thing is clear: this war is not winding down. It’s spreading. And the next few weeks will determine whether Rubio’s optimistic timeline holds — or whether the conflict spirals into something far larger and more dangerous than anyone predicted.
