The United States and Greece just signed off on a $4 billion arms package, and the diplomatic signal that came with it may matter more than the hardware. Secretary of State Marco Rubio closed the sixth US-Greece Strategic Dialogue in Athens on October 7, finalizing Foreign Military Sales that include Stryker armored vehicles and Greece's entry into the US National Guard State Partnership Program, paired with Florida. Rubio then flew to Portugal without setting foot in Turkey, a move only two secretaries of state had made in the past 50 years. The Stryker deal and the State Partnership Program are more significant than they might look. They integrate Greek ground forces directly into US training and logistics systems, which is the kind of institutional link that does not come undone easily. Greece already gives US forces access to Souda Bay in Crete, Larissa, and the northern port of Alexandroupolis, where American LNG now flows north through Bulgaria, Romania, and Moldova into Ukraine. That infrastructure is doing real work. The USS Gerald R. Ford docked at Souda Bay for combat repairs earlier this year, the only Mediterranean port capable of hosting a carrier strike group. Greek-operated Patriot batteries in Saudi Arabia intercepted two Iranian ballistic missiles in March. Athens then moved a Patriot battery from Karpathos to Crete to protect Souda, spending its own limited air defenses to cover American assets. Turkey's trajectory ran in a different direction the same week. On October 5, Ankara joined Saudi Arabia and Pakistan in agreeing to immediately activate their collective defense pact, the Mecca Joint Defence Agreement signed in August, after Houthi missiles started hitting Saudi cities. Turkey is now committing forces to the Gulf, which means air-defense systems it deploys in the Hejaz are not available in the Aegean. According to Modern Diplomacy, analysts are drawing a distinction between how Washington treats the two NATO allies. Turkey is handled as a broker, useful deal by deal, with F-35 access still dangled as a negotiating chip after Ankara was expelled from the program in 2019 over its Russian S-400 purchase. Greece is treated as a plat...
