Trump’s war with Iran, briefly explained

Editor’s note, February 28, 5:30 pm ET: President Donald Trump announced on Saturday afternoon that Iran’s supreme leader, Ayatollah Ali Khamenei, was killed in the airstrikes. The following story was published earlier on February 28, before the news of Khamenei’s death. Welcome to The Logoff: The US is at war with Iran. Hi readers, by now I’m sure you’ve seen the news: Early on Saturday morning, the Trump administration, after a weeks-long naval buildup in the Middle East, launched a major attack on Iran. As always with conflict reporting, there’s much we still don’t know about what has happened, much less what will come next. Trying to follow it all in real time can feel like drinking from a firehose, and this is likely to be a story of weeks and months, not days or hours. With that in mind, here’s what you need to know right now: What happened? The first wave of attacks by the US and Israel, which began around 1 am Eastern time on Saturday morning, targeted multiple Iranian cities, including the capital, Tehran. Hundreds are reportedly dead and many more injured. Iran has responded by striking at targets throughout the region, including Israel and a number of countries in the Persian Gulf that are home to US bases: Qatar, the United Arab Emirates, Bahrain, and Kuwait. So far, there have been no US casualties reported. There are also reports that Iran has blockaded the Strait of Hormuz, through which roughly 20 percent of the world’s oil passes as it makes its way into the global market. Why is the Trump administration doing this? As my colleague Zack Beauchamp reported this morning, Trump’s justifications for war have been bewilderingly incoherent. For much of the week, it has seemed like the possibility of war turned on the outcome of US-Iran negotiations over Iran’s nuclear program (and its ballistic missile arsenal and support for proxy forces like Hezbollah). On Saturday, though, Trump cast the conflict in grander terms: “For 47 years, the Iranian regime has chanted ‘Death to America’ and waged an unending campaign of bloodshed and mass murder,” he said in a video posted to social media. “We’re not gonna put up with it any longer.” Trump is also promising regime change in Iran, on the heels of his threat earlier this year to intervene on behalf of anti-regime protesters; “The hour of your freedom is at hand,” he said on Saturday. What’s the big picture? Saturday’s strikes are Trump’s second norms-shattering use of military force abroad in just the first two months of 2026. But unlike in Venezuela, this looks to be a full-scale war, not a brief operation already over by the time many Americans are tuning in. Iran’s retaliatory strikes against Gulf states on Saturday also raise the possibility that this could further escalate into a broader regional conflict. Trump on Saturday described the US campaign as a “massive and ongoing operation,” and with one aircraft carrier group already in the region and another on the way, the US appears to be positioned for a potential multi-week conflict. What that will look like as it plays out, not even Trump may know: As Reuters reported Saturday, briefers told the president ahead of the attack that it would be a high-risk, high-reward operation.
