Defense Briefing

US defense expert Elbridge Colby has formalized the concept 'NATO 3.0,' which transfers primary responsibility for conventional defense of the continent to European NATO allies – anchored in the new US National Defence Strategy document 2026. Europe is leading in some areas, but remains below requirements in ammunition stocks, artillery, and air defense. This structural shift forces European defense industries to make massive investments and fundamentally changes transatlantic burden-sharing.

Iran's president publicly stated that it is now up to the US to decide whether the ceasefire that has existed since late September will lead to lasting peace – a direct diplomatic signal to Washington. Polymarket assesses the continuation of the ceasefire through September 30 at 99%, while a comprehensive deal (including reconstruction financing) stands at only 17%. The Strait of Hormuz situation and regional instability remain critical risk factors for global energy markets despite the ceasefire.

ISW confirms a largely static trench warfare situation for September 2026: Ukraine has recaptured approximately 973 km² since the start of the year, while Russia achieved net gains of only about 148–650 km². Operation Vivaldi near Lyman demonstrates Ukrainian offensive capability, while Russia continues to exert mechanized pressure in the Pokrovsk-Dobropillia area. Polymarket sees a ceasefire through year-end at 72% – a diplomatic meeting by end of September is already considered 90% likely.

A joint advisory from NSA, CISA, FBI, and over a dozen allied intelligence services confirms that Russian state actors are systematically compromising OT devices (industrial controls, Rockwell/Allen-Bradley PLCs) in energy, communications, healthcare, and defense industries. Simultaneously, attackers manipulated physical controls in US water supply facilities – a first in the escalation level. The Danish military intelligence service also warns of increasing Russian hybrid attacks on NATO allies in the coming months.

NATO Secretary General Mark Rutte designated all allies as 'Eastern Flank nations' at the Copenhagen Military Committee Conference in light of Russia's broad threat. The alliance currently operates 9 multinational battlegroups and the new 'Eastern Sentry' operation, flanked by major exercises such as BALTOPS 26 (20 ships, 6,000 soldiers) and Vigorous Warrior 26 (NATO's largest medical exercise with ~2,000 personnel from 30 nations). Polymarket assesses a direct NATO-Russia clash through December 2026 at 30%.
