Iran: Things are finally starting to feel normal in the Gulf again. On Thursday, three big Saudi oil tankers loaded with about 6 million barrels of crude, sailed right through the Strait of Hormuz. What made that possible? President Trump signed a ceasefire agreement with Iran the day before. And just like that, ships that had been hiding their locations for months started turning their tracking systems back on.

So what exactly happened between Iran and America?

Wednesday saw Trump and Iranian President Masoud Pezeshkian sign a ceasefire memorandum, two days ahead of schedule. The deal essentially opens up the Strait of Hormuz and lifts the American blockade on Iranian ports. According to reports, it is considered the real deal. Oil companies are saying it'll take a while to get shipping back to pre-war levels though. There's still the whole thing about clearing sea routes and checking for mines, but geopolitics can already feel the shift.

Why are oil prices suddenly dropping?

The global oil market didn't waste any time reacting. Brent crude prices fell roughly 2 percent, dipping below $78 a barrel. That's the lowest it's been since the fighting kicked off. Turns out, people were worried about exactly this kind of disruption in the Gulf, and now that worry is easing.

What happens next, is this permanent peace or just a pause?

This agreement actually kicks off 60 days of serious negotiations where both sides will hammer out a long-term solution. Trump launched military operations against Iran back in February with Israeli Prime Minister Benjamin Netanyahu. Now they're talking about peace. But the trickiest part of the whole deal? It's about Lebanon. The agreement says Lebanon's war should be "permanently ended" and its sovereignty protected, something Iran's been pushing for. Except Israel wasn't even at the negotiating table.

What's Israel's problem with all this?

This is where things get messy. Israel started its own military campaign in Lebanon in March, and it's basically occupied large chunks of southern Lebanon claiming it's targeting Hezbollah fighters. On Thursday, Israel released a new map showing it plans to keep even more territory as a "buffer zone." And when asked if they'd leave? Netanyahu's people made it crystal clear: we're not going anywhere.
Israeli jets pounded southern Lebanese towns on Thursday morning, Kafrtebbnit and Jebdeen to be specific. Three people had been died. Meanwhile, Israeli drones were buzzing over Beirut and its southern suburbs. Amid the rows, Iran and America made peace.

Are Trump and Netanyahu still together?

For years they've been tight, but Lebanon just created the biggest political crack between them. Trump's been calling out Israel's tactics lately, destroying entire buildings to get at a handful of Hezbollah fighters. If Trump keeps pushing for an end to the Lebanon war, Israel's got a choice. The choices are either dial back the military operations or risk losing American diplomatic backing.
Trump's team is hinting that the next 60 days of talks could even include a broader deal on Iran's nuclear program. But critics are pointing out that even after all this fighting, Iran didn't just survive, it kept its influence over the Hormuz Strait and scored major relief from sanctions.
