Editor's take

MI5’s warning highlights how warfare has evolved beyond the conventional battles we have traditionally known, increasingly taking on a hybrid character. Cyberattacks, disinformation campaigns and political interference have become new fronts in the confrontation between the West and countries such as Russia, China and Iran, which are accused of using these tactics against the United Kingdom. Consequently, a persistent form of warfare is being waged against Western countries and their institutions below the threshold of open military conflict. MI5 identified Russia as Britain’s “aggressor number one” and raised broader questions about how such attacks should be addressed through collective security mechanisms.

Furthermore, Saudi air defences intercepted a Houthi ballistic missile over Riyadh. While this demonstrates the Saudi-led coalition’s ability to neutralise incoming threats, its effectiveness against sustained saturation attacks remains uncertain. A coordinated barrage combining ballistic missiles, low-cost drones and other projectiles could overwhelm Saudi air defences, exposing vulnerabilities in the Kingdom’s ability to protect its critical infrastructure and population centres.

Pakistan’s test of the Fatah-2 Extended-Range missile, reportedly capable of striking targets up to 400 km away, underscores Islamabad’s continued efforts to expand the range and survivability of its conventional missile arsenal, enabling it to strike deeper into Indian territory. Pakistan’s military has described the missile as hypersonic, although this claim remains unverified, with key technical details, including its actual range and speed, yet to be disclosed. Overall, the test highlights the Pakistani establishment’s sustained investment in strengthening its land-based rocket force and precision-strike capabilities.

Senior US military officials have advocated expanding the scale and frequency of joint military exercises with South Korea, drawing lessons from the war in Ukraine and the need to strengthen combat readiness against an increasingly capable adversary. However, this position contrasts with President Donald Trump’s calls to scale back joint exercises and press Seoul to assume a greater share of the financial burden for its own defence. These competing signals have fuelled concerns in South Korea that Washington could gradually reduce its military commitments to the peninsula. For Seoul, the stakes are particularly high as North Korea continues to advance its missile and nuclear capabilities, while deepening strategic cooperation with Russia. Any perceived weakening of the US security guarantee could prompt South Korea to accelerate its own defence modernisation, increase military spending and reconsider the extent to which it can rely on Washington as the ultimate guarantor of its security. The debate therefore reflects a broader challenge for the US alliance system - balancing demands for greater burden-sharing with the need to reassure allies that American deterrence commitments remain credible.

India’s offer to train the Cypriot Navy reflects New Delhi’s growing strategic engagement in the Eastern Mediterranean and its efforts to deepen defence ties with European partners. The initiative could strengthen maritime security cooperation, improve naval interoperability and create opportunities for defence-industrial collaboration, broadening India’s strategic reach beyond the Indo-Pacific. These engagements could further deepen strategic convergence among India, Greece, Cyprus and Armenia, as they seek to expand defence cooperation and protect their respective regional interests. This growing alignment also needs to be viewed against the backdrop of closer defence ties among Türkiye, Pakistan and Azerbaijan, raising the prospect of competing strategic partnerships across the Eastern Mediterranean, the South Caucasus and South Asia.

1MI5 chief warns of escalating Russian hybrid operations

MI5 Director General Sir Ken McCallum said Russia is increasing sabotage and other hybrid operations against Britain and its allies. He said Moscow is trying to keep these activities below NATO's collective defence threshold. The report's headline also mentions growing threats from Iran and China.

Why it matters: Operations designed to stay under NATO's collective defence threshold make it harder for allies to agree on a response. The warning shows that European security services are treating hybrid activity as a growing and continuing threat.

2Houthi missile aimed at Riyadh intercepted

The Saudi-led coalition intercepted a missile launched by the Houthis towards Riyadh. Saudi civil defence issued alerts through its national early warning platform and later said the danger had passed.

Why it matters: The launch shows that Houthi missile fire towards Saudi cities is still a live threat. The use of the national early warning platform shows how civil authorities alert the public when one is detected.

3Pakistan army test-fires Fatah-2 extended-range missile

Dawn, citing the military's media wing ISPR, reports that the army carried out a successful test launch of the Fatah-2 extended-range missile. The report describes the missile as hypersonic.

Why it matters: Pakistan's successful Fatah-2 ER test signals efforts to expand its conventional precision-strike capabilities and engage targets deeper inside adversary territory. Its claimed manoeuvrability could complicate missile interception, although its actual range and effectiveness remain undisclosed. For India, the development reinforces the need to strengthen early-warning systems and integrated air and missile defences.

4US Army leaders propose more frequent, larger-footprint Korea exercises

After President Trump scaled back a joint exercise with South Korea, a US Army commander called for more frequent drills. The proposed exercises would be modeled on lessons from Ukraine and would have a larger footprint.

Why it matters: The proposal points to a debate within the US military over how to keep up training with South Korea after the reduction. It also shows US Army planners applying lessons from the war in Ukraine to preparations in the Indo-Pacific.

5India offers training assistance to Cypriot Navy

India has offered to support the Cypriot Navy with training, capacity building and technical assistance.

Why it matters: The offer highlights India’s use of training and technical assistance as instruments of defence cooperation with Cyprus. It also reflects the Indian Navy’s expanding blue-water role, as New Delhi seeks to strengthen strategic partnerships and extend its maritime engagement beyond the Indo-Pacific.
