The Age of Connected Crises

A ceasefire that was supposed to stabilise the situation involving Iran and the Israel-Lebanon front this week went nowhere. Neither did attempts to revive talks between Tehran and Washington, President Trump's claims notwithstanding. Hezbollah rejected the Lebanon framework almost immediately, as did Tehran. Israeli strikes on Lebanon continued, while Iranian officials reiterated that any broader understanding with Washington remained tied to developments in Lebanon.

Yet the significance of these events extends well beyond the Middle East.

The wars in Ukraine and the Middle East are increasingly shaping outcomes far beyond their immediate theatres. Their effects are visible not only on battlefields, but also across railways, logistics corridors, energy markets and industrial supply chains stretching from Russia and Central Asia to the wider Asian region.

This is the age of connected crises.

Developments in Ukraine, the Middle East and the Indo-Pacific can no longer be viewed in isolation. Decisions taken in one theatre increasingly affect outcomes in another. Economic disruptions spill across regions. Military commitments in one conflict influence deterrence in others. What is emerging is a more interconnected global order in which instability in one region increasingly shapes both war and economics elsewhere.

Developments in Ukraine, the Middle East and the Indo-Pacific can no longer be viewed in isolation. Decisions taken in one theatre increasingly affect outcomes in another.

Recent developments illustrate this trend. Russia has accelerated work on the International North-South Transport Corridor (INSTC). Freight trains continue moving from China into Iran despite maritime disruptions. The OECD has warned that the Middle East conflict has become the principal threat to global economic growth. Meanwhile, a new study by the Center for Strategic and International Studies (CSIS) concludes that replenishing key US missile inventories consumed during the Iran conflict could take years, creating what it calls a "window of vulnerability" in the Western Pacific.

The Hezbollah Conundrum

The immediate obstacle to stability in the Middle East is that the principal actors are pursuing objectives that cannot be reconciled. A key theme that underscores this contest is religious ideology—a factor that drives both Iran and Israel and produces intractable outcomes.

Lebanon is key to a wider strategic contest involving Iran, Israel and the US. Tehran increasingly treats developments in Lebanon as inseparable from negotiations with Washington over sanctions relief, regional influence and the future of the Strait of Hormuz. Iran seeks to preserve both its deterrent capacity and its regional influence through proxies like Hezbollah and the Houthis. Israel wants to degrade Iran's regional network and destroy Hezbollah's military capabilities.

The US seeks de-escalation without granting Tehran the concessions it seeks. These objectives are simply not compatible. Worse, none of the players—the US, Israel or Iran—are positioned to impose a decisive outcome. The US and Israel have undoubtedly imposed significant costs on Iran and its regional partners. But any further use of military options by the US could cause further damage to the Gulf’s oil and gas.

Both Tehran and Hezbollah retain military capabilities. Iranian influence persists across parts of the Levant and Iraq. Tehran has demonstrated resilience under economic pressure and military attack but lacks the economic strength necessary to establish uncontested regional primacy.

The best outcome could be a limited truce. The underlying issues will remain unresolved.

Trade Corridors and Economic Effects

Much discussion of Iran's relationships with China and Russia focuses on diplomacy, energy or military cooperation. But a key dimension of these relationships lies in trade infrastructure. The war has accelerated a process already underway. Iran is rapidly being integrated into alternative Eurasian transport networks designed to reduce dependence on maritime chokepoints and Western-controlled trade routes.

One example is the fast-developing rail corridor linking Xi'an in China with Tehran, and wider Iran. Freight traffic along this route has increased significantly as Iran seeks alternatives to maritime routes vulnerable to disruption. More important than current traffic volumes are the projects under construction.

China is supporting the development of the Sarakhs railway terminal on the Turkmenistan-Iran border, while plans are underway to electrify approximately 1,000 kilometres of railway from Sarakhs to Razi on the Turkish frontier. This line goes through Iran. Additional track construction is expected to increase freight capacity substantially. Other corridors involving Kazakhstan, Uzbekistan, Turkmenistan and Kyrgyzstan are gradually creating an alternative East-West logistics architecture connecting China, Central Asia, Iran, Türkiye and Europe.

The INSTC, which connects Russia and northern Europe with Iran, the Persian Gulf and South Asia, has become one of the most strategically significant infrastructure projects in Asia. It combines rail, road and maritime routes across multiple corridors. Cargo volumes have increased steadily despite sanctions and geopolitical tensions.

An early completion of the Rasht-Astara railway, which will provide a continuous rail connection between Russia and the Persian Gulf, is particularly important because it strengthens economic integration between Moscow and Tehran while reducing dependence on traditional sea-bound routes.

Together, the INSTC and China's east-west corridors place Iran at the intersection of two major Eurasian connectivity systems. This creates a paradox. Iran remains economically constrained, yet its emerging geographic centrality is vital.

Further, these projects are instruments of strategic resilience. They decrease Iran’s vulnerability to maritime disruption, sanctions pressure and geopolitical shocks. These land corridors do not completely offset Tehran’s vulnerabilities in the Persian Gulf. However, they add significantly to Iranian resilience, preserving critical economic functions during periods of crisis.

This introduces a new dimension to great-power competition. While China, Russia and Iran are investing in rail corridors, logistics networks and alternative trading systems designed to reshape connectivity over decades, the US must now devote increasing resources to rebuilding military inventories consumed across multiple theatres to retain its power.

US defence-industrial manufacturing capabilities are now crucial to any equation. A CSIS assessment in May concluded that the Iran campaign depleted key US missile inventories and created a "window of vulnerability" until stocks could be rebuilt. Replacement timelines for systems such as Patriot interceptors, THAAD missiles and Tomahawks could extend over several years. The concern identified by CSIS is that depleted inventories affect the US' ability to respond to simultaneous crises across the Middle East and the Western Pacific.

The Persian Gulf Constraint

The Trump administration appears to have focused primarily on the military and diplomatic dimensions of the conflict, while paying less attention to its medium-term and longer-term geo-economic consequences. Yet trade routes, logistics corridors and economic interdependencies increasingly shape the strategic options available to states, including Iran, Russia and China.

The economic interlinkages are driving crucial global developments that neither the US administration nor financial markets appear to be pricing in fully, following the AI and data centre frenzy.

The OECD recently warned that the evolving Middle Eastern conflict has become the dominant factor shaping global economic prospects.

According to the OECD, if the conflict is resolved and disruptions are temporary, global growth is expected to ease from 3.4% in 2025 to 2.8% in 2026 before recovering to 3.1% in 2027. However, if the conflict persists, the OECD projects global growth falling to 2.1% in 2026 and 1.8% in 2027. This prolonged disruption scenario would have lasting economic impacts, particularly on countries in Asia, Europe, and developing economies most exposed to higher energy and food prices. The Strait of Hormuz and oil and gas remain central to any economic outlook.

Politically, Washington remains indispensable to any future settlement. Yet it has struggled to articulate a coherent pathway towards an effective resolution of the current crisis, let alone a durable one.

Contradictory threats of escalation have coexisted with efforts to reopen dialogue. Public disagreements with Israeli leadership have occurred alongside continued strategic cooperation. It’s a struggle to determine whether American policy reflects strategic flexibility or strategic incoherence.

The Persian Gulf illustrates the dilemmas confronting both Washington and its Arab partners. For the US, the challenge is no longer about deterring Iran from possessing a nuclear device. Indeed, on this issue Trump might have painted himself into a corner.

American efforts to balance military pressure with diplomatic engagement have created uncertainty among its Middle East partners about Washington's long-term intentions. For the Gulf Cooperation Council (GCC) states, the dilemma is equally acute. They remain dependent on the US for security guarantees, advanced military capabilities and deterrence against Iran.

Yet they also recognise that Iran cannot be geographically excluded from the regional order and that economic stability depends on avoiding a prolonged confrontation. The GCC states do not want to be collateral damage in a wider US-Israel-Iran contest. Saudi Arabia, the UAE, Qatar and Oman therefore find themselves pursuing a triple-track strategy: maintaining security ties with Washington while simultaneously preserving channels of communication with Tehran and expanding economic relationships with China. The ideological differences with Israel and the Palestine issue remain another intractable issue, with only the UAE and Bahrain opting for any level of pragmatism.

The China Factor

China's trade infrastructure play, and its broader geopolitical strategy, deserve special attention. China is Iran's largest trading partner, its principal energy customer and a major source of infrastructure investment. Beijing possesses significant economic leverage over Tehran. China can exert pressure, but it chooses not to, at this moment.

It’s vital to understand why. China's objective is not to encourage unlimited Iranian escalation. Beijing's primary interest is preserving a strategic environment that protects Chinese economic interests while constraining American influence. A weakened but resilient Iran serves this purpose better than either a collapsed Iran or an Iran fully integrated into a Western-led order.

This logic extends beyond the Middle East. Chinese investments in Eurasian transport corridors are frequently interpreted solely through the lens of commercial opportunity. They should also be viewed through the lens of strategic redundancy. Alternative overland corridors linking China with Central Asia, the Middle East and Europe possess strategic value extending far beyond their immediate commercial returns, decreasing vulnerabilities arising from the maritime corridors. Iran is central to this strategy.

This is where the connection between Ukraine, the Middle East and Taiwan becomes most significant. Russia is geographically crucial to any land corridor equation. The trajectory of Russia's war against Ukraine will shape Moscow's capacity to support Iran, influence energy markets and participate in future diplomatic settlements.

Instability in the Middle East benefits Russia through higher energy prices and increased pressure on Western economies. A Russia that emerges largely unscathed from the Ukraine war will retain substantial leverage across an unstable Middle East, furthering its ability to influence US deterrence capacity over Taiwan.

Crises are no longer regional events. They are components of an interconnected global system.

What is emerging is a new phase of global competition in which developments in Ukraine, the Middle East and the Indo-Pacific are increasingly inseparable. Trade corridors stretching across Eurasia influence the resilience of states involved in distant conflicts. The war in Ukraine shapes developments in the Middle East. Events in the Middle East influence military planning in the Indo-Pacific. As these connections deepen, outcomes in one region will increasingly affect outcomes in the others. Crises are no longer regional events. They are components of an interconnected global system.
