A curated daily news digest by mullso

Top Stories

1. Trump Walks Back Iran Energy Strikes — Markets Whipsaw
The biggest story of the day: President Trump signaled a delay in planned strikes on Iranian energy infrastructure, claiming "very good and productive" talks with Tehran. Markets swung violently — oil plunged 10% before steadying, stocks reversed heavy losses, and gold seesawed. The catch? Iran flatly denied any direct talks took place. The FT reports that $580 million in oil bets were placed just 15 minutes before Trump's Truth Social post, raising serious questions about information leakage.

2. Israeli Military Strikes Tehran, Netanyahu Pushed for Joint Khamenei Killing
Reuters reports that Netanyahu personally argued to Trump for a joint operation to kill Iran's Supreme Leader Khamenei — and that Trump approved a broader Iran operation based on that pitch. Meanwhile, the Israeli military confirmed it conducted strikes in Tehran today. The civilian toll continues to mount on all sides.

3. LaGuardia Crash Kills Two Pilots
An Air Canada regional flight (AC8646) collided with a fire truck at LaGuardia Airport, killing both pilots. The aircraft was described as looking "like it got cut in half." US Transportation Secretary Sean Duffy credited seatbelts with saving passenger lives. NTSB investigation underway.

4. Slovenia First EU Country to Introduce Fuel Rationing
The Iran conflict's economic ripple effects are becoming real: Slovenia became the first EU nation to impose fuel rationing, capping purchases at 50 liters per day. With European energy supplies under threat, other nations may follow.

5. iPhone 17 Pro Runs a 400B Parameter LLM Locally
