War widens in the Black Sea in a test of NATO red lines

In recent weeks, a maritime war has been escalating in the Black Sea, testing NATO's red lines. Seven cargo ships were struck near NATO members Romania and Bulgaria in October alone, followed by the sinking of a Greek container ship in Bulgaria's exclusive economic zone. These attacks, which military analysts attribute to Russian forces, have left littoral member states vulnerable.

Sidharth Kaushal, a senior fellow at RUSI think-tank, describes this as an "undeniably an escalation." Russia denies targeting Ukraine's neighbors with drones and blames European governments' military aid for escalating the war in Ukraine. The attacks seem to be testing NATO's reaction to this red line, with Russia aware that it will only deploy minimal measures.

NATO officials emphasize that these actions are a serious security threat to the alliance's commitment to defending all its members, including those in the Black Sea. Romania, a crucial trade route for its offshore Neptun Deep gas project, has accused Russia of systematic strikes on civilian ships but has not attributed individual attacks due to the need for forensic evidence.

Bulgaria has not blamed Russia but noted that some attacks seem to benefit Russia. The surge in strikes on Black Sea shipping has significantly impacted trade and exports, forcing Russia and Ukraine to seek alternative routes. Ports have been damaged, and exports have plummeted, with Russia exporting only a fraction of the grain it once did through the Black Sea and Sea of Azov.

NATO's attention has primarily focused on the Baltics and Poland, leaving Romania's requests for surface-to-air interceptors and radar systems unaddressed.
