The United States is no longer a supporting actor in the spiraling Israel-Iran war. What began on February 28 as joint U.S.-Israeli strikes has hardened into a broader regional conflict, pulling Washington deeper into military, diplomatic and economic consequences that now stretch far beyond Israel and Iran. The war has already killed more than 2,000 people across Iran, Lebanon, Israel, Iraq and Gulf states, while attacks on shipping, oil infrastructure and U.S. facilities have transformed a Middle East crisis into a global one.
For Israel, the campaign is being framed as a strategic effort to break Iran’s missile and nuclear capabilities and potentially create conditions for long-term regime collapse. Israeli officials said this week that the war has already achieved major gains, even as they acknowledge the fighting is not over. That claim was paired with another sharp escalation: Israeli strikes reportedly targeted or killed senior Iranian figures including Ali Larijani, one of the most powerful surviving officials in Tehran, and Gholamreza Soleimani, the head of the Basij paramilitary force. Iran has not fully confirmed all of those deaths, but the message from Israel is unmistakable — it is trying to decapitate Iran’s security leadership while keeping up pressure on Hezbollah and other Iran-linked forces across the region.
For Iran, the answer has not been surrender but expansion. Tehran and Iran-aligned groups have continued missile, drone and rocket attacks against Israel, Gulf infrastructure and U.S. interests, including a major assault on the U.S. embassy compound in Baghdad. At the same time, Iran’s leadership has signaled little interest in quick de-escalation. Reuters reported that Iran’s new supreme leader, Ayatollah Mojtaba Khamenei, rejected proposals relayed by intermediaries and demanded that the U.S. and Israel first accept defeat. U.S. intelligence assessments described by the Washington Post suggest that instead of collapsing, Iran’s system is consolidating under harder-line control, particularly through the IRGC.
That leaves the United States in a brutally uncomfortable position: militarily committed, politically divided and strategically exposed. A top U.S. counterterrorism official, Joe Kent, resigned in protest, saying Iran had not posed an immediate threat to the United States, underscoring fractures inside Washington over the rationale for the war. At the same time, the conflict has already inflicted real costs on the U.S. military and on the White House politically, as attacks on American positions multiply and the administration faces growing scrutiny over whether it fully anticipated Iran’s capacity to retaliate across the region.
The economic blowback is rapidly turning this into an American domestic story too. Iran’s disruption of the Strait of Hormuz — one of the world’s most vital energy chokepoints — has shaken oil and fuel markets, pushing Brent crude near or above $100 a barrel and sending U.S. diesel prices sharply higher. Financial Times reported U.S. diesel nearing $5 a gallon, while Reuters warned that fears of much steeper oil spikes are no longer far-fetched if the disruption continues. The war is now hitting trucking, farming, shipping and inflation expectations, meaning the battlefield consequences are showing up at fuel pumps and in supply chains thousands of miles away from the Gulf.
Internationally, the war has also exposed the limits of U.S. coalition-building. European officials have urged Washington and Jerusalem to end the fighting, but they have shown little appetite for joining a military effort around Hormuz, especially after complaining they were not meaningfully consulted before the conflict began. Regional governments are also trying to avoid being dragged further into the confrontation, even as Iranian retaliation has already reached Gulf territory. The result is a dangerous imbalance: the U.S. has the power to intensify the war, but far less international backing to stabilize its aftermath.
So the conflict now looks less like a short, decisive campaign and more like a grinding regional war with no clean off-ramp. Israel believes it has badly damaged Iran. Iran is proving it can still inflict pain. The U.S. is trying to project control while absorbing rising military, economic and diplomatic costs. And the rest of the world is watching a confrontation that could still widen further — not because anyone clearly wants a larger war, but because every side now seems trapped inside one.
