Defense Briefing

Trump stated publicly that the US wanted to 'help' Israel, the Middle East, and 'itself' in the Iran war – while the US military attacked new targets in Iran on September 1. Polymarket rates an effective ceasefire through September 4 at still 62%, but the probability of diplomatic talks by end of September has fallen 54% month-over-month. The escalation strains energy markets and ties up US capacities, increasingly pressuring European defense and Indo-Pacific strategy.

Following Khamenei's death from US-Israeli strikes in February 2026, Polymarket sees an 83% probability of his son Mojtaba Khamenei becoming Iran's new head of state by year-end – a hitherto little-noticed power transition with strategic significance. A consolidated regime under Mojtaba could further lower willingness to negotiate and prolong the war. For energy markets and Western sanctions policy, Iran's leadership question is a central uncertainty factor.

A new analysis by INFORMNAPALM shows that Russia's long-range drone campaign reveals operational gaps in Europe's air defense that NATO members have so far been unable to close – procurement bottlenecks and lacking deep-strike capabilities are the core problems. Lessons from Ukraine are being discussed, but structurally have not yet been incorporated into NATO planning. Particularly given the Pentagon troop reduction review, Europe will be forced to scale up its own defense capacities significantly faster.

Despite European NATO defense spending estimated at USD 639 billion in 2026 and the Hague target of 5% GDP, mistrust among allies is growing as the US increasingly acts transactionally and focus drifts to the Indo-Pacific. The IISS warns that transparency in spending is lacking and headline figures mask structural deficiencies. This erosion of trust is strategically more dangerous than the funding gap itself, as it undermines the collective deterrence logic.

Following US-Israeli military strikes, Iran has significantly intensified its cyberattacks on critical US infrastructure – particularly water and energy systems in at least 12 states. The Pentagon expects to release a new cyber strategy doctrine next week in response to escalating OT attacks. The hybrid nature of the Iran war – conventional plus cyber – presents Western defense planning with a qualitatively new challenge.
