The continuing U.S.–Iran conflict remains the most significant immediate area of concern. Direct military exchanges are continuing, with U.S. forces striking Iranian oil carriers after Iran launched ballistic missiles towards U.S. Navy vessels. Tehran is warning that further attacks will bring a more severe response. At the same time, increasing economic pressure appears to be weakening Iran’s leverage over the Strait of Hormuz, and discussions continue over a possible shipping arrangement that could provide a limited diplomatic off-ramp.

Iran’s nuclear programme remains a separate and increasingly important concern. The United States, Britain, France, and Germany are seeking an IAEA Board referral of Iran to the UN Security Council over Tehran’s continuing refusal to provide inspectors access to bomb-damaged nuclear facilities and information needed to verify its enriched-uranium stocks. Iran’s approximately 440.9 kilograms of uranium enriched to 60% remains unverified, while proposals within the Iranian parliament to withdraw from the Nuclear Non-Proliferation Treaty remain under observation.

Russia’s war against Ukraine and the possibility of escalation involving NATO also remain under close observation. Russian Foreign Minister Sergei Lavrov has described German accusations over the Leipzig drone incident as effectively the beginning of a “real war”, adding to increasingly sharp Russian rhetoric towards NATO states. Separately, public discussion within Russia over possible tactical nuclear use in Ukraine has become more explicit. There is no evidence that Russia has decided to employ nuclear weapons or is making operational preparations for their use, but the widening debate itself is significant. Meanwhile, U.S. envoys have met both Russian and Ukrainian leaders in renewed efforts to end the war, providing a potentially stabilising diplomatic countertrend.

The Zaporizhzhia nuclear power plant has also become an immediate radiological-safety concern. The facility has been without external electrical power since 20 August and has depended on emergency diesel generators. The IAEA has brokered a temporary ceasefire around the plant to allow repairs to damaged power lines, an important risk-reducing measure intended to prevent a potential station blackout.
