🌍 WHAT'S HAPPENING IN THE WORLD

Here's what's shaping the world today.

Global Markets Steady After a $1 Trillion AI-Valuation Sell-Off

World markets clawed back ground on Wednesday after two punishing sessions that wiped out close to a trillion dollars in technology value, driven by mounting investor anxiety over stretched artificial-intelligence valuations and a sharp slide in privately held SpaceX. S&P 500 and Nasdaq futures edged higher as chip and AI names stabilized, with traders eyeing Micron's earnings for a read on whether demand for memory and data-center hardware is holding up. The U.S. dollar, meanwhile, climbed to a 13-month high on safe-haven buying and shifting expectations for the Federal Reserve. The episode is a reminder of how concentrated global markets have become in a handful of AI-exposed companies — when sentiment toward AI turns, the whole index feels it.

Rubio Tours the Gulf as Allies Seek Answers on the Iran Peace Deal

U.S. Secretary of State Marco Rubio opened a Middle East tour this week as Gulf partners press Washington for specifics about the recently brokered deal that paused the Iran war. Several Gulf governments remain skeptical about how durable the arrangement is and what security guarantees, if any, underpin it. Pakistan, credited with helping broker the peace, is drawing diplomatic praise that analysts say could translate into economic and strategic dividends for Islamabad. The diplomacy underscores how much of the region's stability now hinges on a fragile understanding that all sides are still testing.

North Korea Commissions a Destroyer and Sets a Two-Warship-a-Year Goal

North Korea has placed a roughly 5,000-ton destroyer into service, with leader Kim Jong Un calling it a symbol of the country's growing naval power and signaling an ambition to arm the fleet with nuclear weapons. At the commissioning, Kim said the country should build two large warships of similar size every year for the next five years — a rapid build-out that would reshape naval dynamics in the region. Regional neighbors and the United States are watching closely, as a nuclear-capable navy would mark a significant strategic shift. Outside experts caution that ambitions and shipyard capacity are not the same thing, and questions remain about how quickly Pyongyang can actually deliver.

_Before we move on, here's one to hold onto._

After decades of decline, the world's mangrove forests have staged a remarkable global comeback. A new study in the journal _Science_ finds that gains have outpaced losses over the past 16 years, leaving only a one-percent net decline in total area across four decades — and existing forests are growing denser and healthier thanks to conservation and restoration work. Researchers from Tulane University called it a "rare conservation success story" and "an important source of optimism for climate action," since mangroves shield coastlines from storms, store vast amounts of carbon, and serve as nurseries for fish. The momentum is building elsewhere on the water, too: French Polynesia just announced a marine reserve the size of France, roughly 200,000 square miles around the Austral and Marquesas Islands, with the highest level of protection from mining, trawling, and industrial fishing. It's proof that even the hardest environmental trends can bend back in the right direction.

_Okay. Now, the tech._
