Trump foreign policy 2026, Iran nuclear threat, North Korea hypersonic missiles, US national security, global conflict risk 2026

North Korea upgraded its nuclear arsenal in 2025, significantly enhancing its military legitimacy. Kim Jong Un has ordered a radical expansion of missile and shell production for 2026.

Pyongyang began 2026 by testing ballistic missiles involving a hypersonic weapons system. These missiles flew about 900 kilometres, designed to evade modern interception technologies.

Trump has expressed strong interest in resuming dialogue with Kim Jong Un, even alluding to sanctions relief. However, Pyongyang remains cautious following the 2019 Hanoi negotiations and has not yet responded.

By mid-2025, Iran possessed over 400 kg of 60 per cent enriched uranium, enough for nearly 10 weapons. Tehran officially ended the 2015 JCPOA in October 2025, declaring all nuclear restrictions void.

In early 2026, deadly protests hit dozen of locations across Iran, with at least 16 people killed. Trump has warned he is "locked and loaded" to intervene if the regime continues using lethal force.

The Trump administration has revived "Maximum Pressure," causing renewed polarisation in the Middle East. Some Gulf nations support this pressure, while others fear the unpredictability of a trapped Iranian regime.

Despite previous strikes, the IRGC is mass-producing advanced missiles using new equipment from external partners. The strategy focuses on "deterrence through volume" to overpower Israeli and US missile defences.

North Korea and Iran are increasingly linked through military cooperation with Russia. This "axis" presents a unified anti-Western coalition that challenges US interests globally in 2026.

US intelligence expects Iran to remain a pressing foreign threat to critical US infrastructure via cyberattacks. These disruptive attacks aim to have cascading impacts on various US industries and public safety.
