If the Diego Garcia strike report is accurate, then one of the central assumptions about Iran’s missile program has just collapsed. For years, the accepted ceiling was around 2,000 kilometers. A ballistic missile reaching Diego Garcia suggests something in the neighborhood of 4,000 kilometers, which pushes it out of the medium-range category and into the intermediate-range class (IRBM). That is a strategic leap. The real story is not whether the missile was intercepted. It is that Iran may have demonstrated reach far beyond what much of the world believed it possessed. A 4,000-kilometer capability changes the map. Major European capitals begin to enter the conversation. Paris comes into range. London moves much closer to the edge of vulnerability depending on launch point and payload. This would mean the missile threat is no longer confined to the Gulf, Israel, or parts of South Asia. It would mean the radius of deterrence, defense, and fear has expanded dramatically. If confirmed, Diego Garcia was not just a target. It was a message.

Hormuz GPS disruption continues GPS interference in and around the Strait of Hormuz has continued to rise since the crisis began, suggesting a persistent and geographically dispersed campaign of electronic disruption. This interference is triggering false AIS positioning, causing ships to appear in locations where they are not. For operators and analysts, that means greater uncertainty around vessel tracking, maritime safety and the reliability of situational awareness in one of the world’s most strategically significant waterways.

Geography favors Iran in any war to open Hormuz. The shipping lanes are so narrow tankers and Naval escorts are sitting ducks. Perfect for Iran’s drones and mines. Trump is caught in the Escalation Trap — doubling down only makes things worse

[🌍#Golfe] Dans une région parmi les plus arides du monde et où la disponibilité de l'eau est dix fois inférieure à la moyenne mondiale selon la Banque mondiale, les usines de désalinisation ont un rôle vital pour l'économie et la consommation d'eau potable de ses millions d'habitants. Environ 42% de la capacité mondiale de dessalement est présente au Moyen-Orient, montre une récente étude publiée dans la revue Nature. Aux Emirats arabes unis, 42% de l'eau potable provient de ces usines, 90% au Koweït, 86% à Oman et 70% en Arabie saoudite, détaille une note de l'Institut français des relations internationales (Ifri) de 2022. ⤵️ information.tv5monde.com/international/…

Maps from Flightradar 24 show that air travel between Europe and Asia is increasingly becoming a challenge. There are only two corridors left which allow uninterrupted travel. Extending the current war to Turkey, Azerbaijan and Oman - three countries which already have to deal with Iranian drones and missiles - will further complicate matters.
