Defense Briefing

Iran has for the first time since the April ceasefire fired ballistic missiles and drones at Israel after Israel attacked Beirut. Polymarket rates the probability of a lasting US-Iran peace deal by June at only 44–68%, with a downward trend. Trump called for restraint, but Israel continued counterattacks – the ceasefire is effectively considered failed.

New ISW and OSINT data show: Ukraine achieved net +242 km² territorial gains in May 2026 (April: +116 km²) and increasingly dominates drone warfare. Russian drones struck a nuclear fuel storage facility near Chornobyl for the first time, intensifying the escalation dimension. Polymarket sees a ceasefire by end of 2026 at only 46% – attrition continues.

Italy's Defense Minister Crosetto openly advocates for an independent European defense alliance beyond NATO structures, while France and Cyprus simultaneously sign a bilateral defense pact with French troop deployment. This signals structural fragmentation of European security architecture – individual states seek bilateral solutions instead of joint EU defense. The initiative comes during a phase when European NATO spending is expected to rise to around €800 billion by 2030.

Anthropic's AI model 'Claude Mythos' reportedly autonomously identified thousands of zero-day vulnerabilities – cybersecurity experts speak of the first official 'AI Shock Event'. In parallel, the AFCEA conference warns of 'grim' risks to US and European critical infrastructure from state actors in China, Iran, and Russia. The explosion of AI-powered attack tools structurally changes the threat landscape and renders classical vulnerability management nearly ineffective.

The US State Department reportedly internally classified Turkey as the 'next Iran' – explosive given that Ankara as NATO's second-largest military simultaneously supplies European states with weapons systems and hosts the NATO summit. The incident illustrates growing tension between transactional US foreign policy and NATO cohesion. A break with Ankara would redefine the southeast European flank and Bosporus control in security terms.
