The US and Iran have been fighting on and off since February 2026, when a US-Israeli strike killed Iran's Supreme Leader Ali Khamenei. An April 7 ceasefire held for months, then broke down. Iran attacked shipping in the Strait of Hormuz in July. The US bombed Iran's Larak Island on August 30, and Iran hit US bases in Jordan that same day. Early Saturday, Iran's Revolutionary Guard fired ballistic missiles at a US aircraft carrier and a guided-missile destroyer near the Strait of Hormuz. Both ships evaded the missiles, and US Central Command says no Americans were hurt. The US then hit three Iranian oil tankers, disabling the M/T Downy off Kharg Island and the M/T Stark 1 near Jask, and destroying the unladen M/T Kylo in the Gulf of Oman after ordering the crew to abandon ship. Iran's state broadcaster confirmed a tanker was hit near Kharg Island.

1. The Pentagon Calls This Deterrence (Admiral Brad Cooper, Sen. John Cornyn)

Hit Iran harder than Iran hits the US, and Tehran will think twice next time.

Cooper's goal is simple. CENTCOM commander Admiral Brad Cooper wants Iran to pay more than it dishes out. He framed the tanker strikes as a deliberate cost multiplier: "If you shoot at two of our ships, we will impose an even higher economic cost — taking out three of yours."

This was already policy. CENTCOM had announced a "tanker for tanker" retaliation policy on September 2, three days before Saturday's strikes, alongside hits on Iranian air defense sites and radar systems.

Some senators were already cheering this approach back when the war started. Sen. John Cornyn said when the US and Israel first struck Iran in February: "With today's strikes by U.S. forces led by our Commander-in-Chief, President Trump, there is finally an opening for these dark days to come to an end."

2. Congress Already Voted to End This War (Rep. Thomas Massie, Rep. Ro Khanna, Sen. Susan Collins, Sen. Bill Cassidy, Sen. Lisa Murkowski, Sen. Rand Paul)

A bipartisan majority in both chambers formally told Trump to end the war, and he didn't listen.

Congress didn't just ask — it voted. Reps. Thomas Massie and Ro Khanna's war-powers resolution failed in the House in March, but the House brought it back and passed it 215-208 on June 3. Three weeks later, on June 23, the Senate passed the same resolution 50-48 — the first time in the war a war-powers measure cleared both chambers.

Four Republicans broke with the president to make that happen. Sens. Susan Collins, Bill Cassidy, Lisa Murkowski, and Rand Paul crossed over to vote with Senate Democrats. One Democrat, Sen. John Fetterman, voted no.

The vote didn't stop the war, because it couldn't. A concurrent resolution never goes to the president's desk, so it never reached Trump, and it carries no legal force. It's a formal statement of Congress's position, not a binding order. Trump called the June House vote "meaningless," dismissing it as the work of "4 bad Republicans and all of the Dumocrats."

The House tried again in July. It passed a second resolution 214-208. The Senate rejected a similar measure the same day, 47-49. The White House told lawmakers the resolutions "don't have the force of law" and that Trump "has the Constitutional authority to defend the United States."

3. Iran Says It's Only Defending Itself (Iranian state broadcaster IRIB, Foreign Ministry spokesman Esmaeil Baqaei)

Tehran's public account of Saturday left out the part where its own forces fired first.

State TV's version of Saturday skips a step. IRIB reported that four US missiles struck a tanker near Kharg Island and that the crew evacuated. It didn't mention the IRGC missile attack on US Navy ships that CENTCOM says came first.

Iran's made this move before. In a September 4 statement about separate strikes on US forces in Qatar, Foreign Ministry spokesman Esmaeil Baqaei called Iran's own strikes defensive and said they hit only military targets. He accused the US of hitting "schools, hospitals, residential neighborhoods, wedding ceremonies, bridges, and more."

Iran's military has already promised worse if the US keeps hitting it. Iran's military command said September 1 that further US strikes would draw "crushing and devastating blows" against American forces.

Where This Lands

The Pentagon says Saturday's strikes were proportional deterrence: hitting three tankers for two missiles makes further attacks more expensive for Tehran. Congress says it already settled this question. Both chambers passed a resolution in June ordering an end to the war, and the House passed a second one in July. The administration says neither one carries legal weight, and it hasn't followed either. Iran's government says it's absorbing attacks, not launching them, but its own account of Saturday leaves out the missiles CENTCOM says Iran fired first. No ceasefire is in place as of Saturday morning.
