Defense Briefing

Iran has officially closed the Strait of Hormuz following renewed massive US strikes – a waterway through which approximately 20% of global oil trade flows. According to Pentagon statements, the US has announced further strikes, while Iran has responded with rocket attacks on US military bases in Gulf states and Jordan. The oil futures market is reacting with sharp price spikes; the economic consequences for Europe and global supply chains are immediately felt.

Russia is deliberately building infrastructure near the European NATO border and plans the permanent deployment of up to 115,000 soldiers – a direct threat display against the alliance for the period after the Ukraine war. The British Prime Minister warns in parallel that Russia could directly attack NATO within four years. This development forces European NATO members to fundamentally realign their defense planning.

The US Department of Defense has officially announced its intention to 'rightsize' its contribution to the NATO Force Model – Undersecretary Elbridge Colby is leading the initiative, with Europe to assume primary responsibility for its conventional defense. Simultaneously, a new survey shows that only one in ten Europeans views the USA as a reliable ally. Europe thus faces the concrete task of building an independent deterrence architecture within a few years, which €513 billion in defense spending in 2026 already reflects.

France launched the 'Forward Deterrence Initiative' in March 2026, which explicitly provides for an extension of the French nuclear umbrella to European partners – a direct response to the waning US security guarantee. Analysts assess the interplay with NATO nuclear doctrine as a novel and complex strategic architecture. This is the most significant shift in European nuclear policy in decades and could fundamentally strengthen the EU's strategic autonomy.

Parallel to the kinetic conflict, Palo Alto Networks documents an Iranian cyber campaign deliberately targeting US energy networks, transportation systems, and FIFA World Cup infrastructure in host cities. The Pentagon has tasked its Cyber Defense Command with developing a new plan to protect critical infrastructure, while the DoD allocates $14.3 billion for cyber operations in the FY2026 budget. The interweaving of conventional warfare and cyber warfare against civilian infrastructure marks a new escalation level.
