Geopolitics & Sovereign Positioning

Japan's position on the Iran conflict reveals the limits of collective defence when the U.S. initiates preemptive action. Prime Minister Takaichi offered rhetorical support that Foreign Policy reports President Trump publicly praised, but Tokyo remains cautious about deploying Self-Defense Forces to the Strait of Hormuz. The Diplomat notes the key constraint is how Japan classifies the situation legally — collective self-defence provisions require Japan to be defending an ally under attack, complicated by the conflict originating in U.S. strikes rather than Iranian aggression against American territory. This creates a precedent problem: allies with constitutional or political constraints on offensive operations may withhold support when Washington initiates conflict, even if they share strategic interest in countering Iran.

The hesitation extends beyond Japan. Chatham House analysis notes that despite possessing capable air forces that could complement U.S.-Israeli strikes on Iranian missile infrastructure, Gulf Arab states including Saudi Arabia and UAE show remarkable restraint despite being struck by Iranian projectiles. The risks of direct participation — becoming priority Iranian targets, economic disruption, domestic political backlash — outweigh American pressure. What emerges is a coalition structure where the U.S. and Israel bear operational burden while partners offer basing, overflight, and intelligence support but avoid direct combat roles.

Foreign Policy reports Ukraine is attempting to capitalise on its battlefield-developed counter-drone technology by offering systems and expertise to Gulf states facing Iranian drone threats. Kyiv possesses operational knowledge from defending against sustained Russian drone campaigns and has developed integrated detection and kinetic/electronic countermeasures. However, significant hurdles exist: Gulf states have existing relationships with Western and Israeli defence contractors, Ukraine lacks diplomatic recognition from some Gulf countries, and most critically, Ukraine faces its own severe weapons shortage as it develops home-brew long-range missiles to compensate for constrained Western supplies.

The dynamic illustrates how prolonged conflict creates dual pressures — Ukraine needs revenue and strategic partnerships to sustain its own war effort, but exporting capabilities means diverting production capacity or revealing operational techniques. The Gulf market is substantial but competitive, and Ukraine's value proposition depends on recent combat validation rather than established supply chains or integrated support systems that traditional defence exporters provide.

War on the Rocks documents that over 100 senior PLA officers have been removed since 2022, with nine purged last week and three retired generals removed from advisory positions in early March. The January removal of China's top general Zhang Youxia represents the most significant case. The analysis argues these purges are not aberrations but structural features of the PLA system, driven by Xi's centralisation of authority, zero-tolerance for corruption that is endemic in military procurement and promotion, and concerns about loyalty during a potential Taiwan contingency. The scale suggests Xi lacks confidence in the PLA's combat effectiveness or political reliability despite years of modernisation and increased defence spending.

The purges create operational risks: they disrupt command relationships and institutional knowledge, create incentives for risk-averse behaviour among surviving officers, and signal that political loyalty matters more than professional military competence. For foreign assessments of Chinese military capability, this introduces a variable beyond hardware counts — whether the PLA officer corps can execute complex joint operations under pressure when leaders are selected partly for political criteria and fear making decisions that might later be characterised as corruption or disloyalty.

The Diplomat reports that South Korean weapons systems are now operationally involved in the Iran war, exposing what the analysis calls a long-standing blind spot in Seoul's defence industry model: the operational and political consequences of weapons being used in conflicts where Korea has no direct stake. South Korea has rapidly expanded defence exports to become a top-tier supplier, driven by competitive pricing, modern technology, and willingness to offer flexible financing and technology transfer terms that traditional suppliers often withhold. Major customers include Poland, Australia, and multiple Middle Eastern states.

The Iran war involvement creates a policy dilemma. If South Korean systems perform well, it validates the export model and may generate additional orders — but it also ties Seoul to conflicts it has not chosen and may complicate relations with Iran or other states. Unlike major suppliers like the U.S., France, or Russia who integrate arms sales into broader strategic frameworks, South Korea has largely treated defence exports as commercial transactions with insufficient consideration of how weapons use might constrain future diplomatic options or create obligations to support customers in conflicts.

The Diplomat reports Taiwan is launching New Southbound Policy 2.0, expanding beyond the original focus on Southeast and South Asian countries to include broader partnerships with democratic states globally. The initiative aims to deepen economic ties, technology cooperation, and people-to-people exchanges as Taiwan seeks to reduce dependence on China and build resilience against economic coercion. The expansion reflects lessons from the original NSP launched in 2016 — while successful in diversifying some trade and investment, Southeast Asian countries remain cautious about antagonising China through overt Taiwan alignment, limiting the policy's strategic impact.

The 2.0 version appears designed to work around this constraint by building diffuse networks of technological and economic interdependence with democracies rather than seeking formal diplomatic breakthroughs. Taiwan's position as a critical node in semiconductor supply chains and emerging AI infrastructure provides leverage. The approach implicitly accepts that most countries will not risk Chinese retaliation by upgrading formal Taiwan relations, but many will quietly deepen functional cooperation in technology, supply chains, and standards-setting where Taiwan offers unique capabilities.
