Iran-Israel War 2026: US Intervention, Global Impact & the End of the Rules-Based Order

The Shifting Sands of Global Power: After the Fall of Khamenei

The death of Ayatollah Ali Khamenei on February 28, 2026, marks not just the end of an era for Iran, but a potential inflection point in a rapidly destabilizing global order. The coordinated strikes by Israel and the United States, and the subsequent escalation of conflict in West Asia, have exposed deep fractures in international alliances and highlighted the limitations of traditional diplomatic approaches.

A Cascade of Conflict: From Nuclear Talks to Regional War

The attack on Khamenei was the culmination of a three-year period of escalating tensions, beginning with missile exchanges in April 2024. Despite ongoing, albeit ultimately unsuccessful, negotiations regarding Iran’s nuclear program, the situation deteriorated, leading to the February 28th bombing. President Trump’s assertions of having “obliterated” Iranian nuclear facilities and “decimated” military capacities should be viewed with caution, mirroring previous statements that proved inaccurate.

Collateral Damage: The Global Ripple Effect

The conflict’s impact extends far beyond the immediate region. The closure of the Strait of Hormuz, a critical artery for global oil supplies, has triggered economic disruption. Rising oil prices, supply chain interruptions, and transportation challenges are impacting economies worldwide. The conflict has also led to casualties in neighboring countries, from Türkiye to Oman, with thousands already affected.

Pro Tip: Geopolitical instability often leads to increased volatility in financial markets. Diversifying investment portfolios and closely monitoring global events are crucial strategies during times of conflict.

The US Role: Diffuse Unilateralism and Shifting Alliances

The current US approach, characterized as “diffuse unilateralism,” represents a departure from previous interventions. Unlike the Gulf War in 1991 or the NATO intervention in Libya in 2011, the recent actions lacked broad multilateral authorization or the formation of a robust coalition. This suggests a willingness to act independently, even at the expense of traditional alliances. The US has increasingly relied on displays of military strength and selective deals, rather than institutional investment in global governance.

Europe’s Dilemma: Between Norms and National Interests

The European Union finds itself caught between supporting its US ally, upholding democratic values, and navigating internal divisions. The war has exposed the limitations of Europe’s ability to enforce a rules-based international order, with member states grappling with conflicting priorities. The EU’s response has been hesitant, reflecting a broader crisis of confidence in its role on the global stage.

The BRICS+ Response: A Silent Observer?

The silence from Iran’s allies within the BRICS+ group is notable. While Iran recently joined the alliance, the group has not issued a unified statement regarding the conflict. This suggests a degree of caution and a reluctance to openly challenge the US and Israel. Russia, though, has offered to mediate a deal, potentially seeking to leverage the situation to its advantage in the ongoing standoff with the West.

Succession and Internal Instability in Iran

The death of Khamenei has ushered in a period of uncertainty in Iran. His son, Ayatollah Mojtaba Khamenei, has assumed the role of Supreme Leader, but reports indicate he was injured in prior Israeli bombings and has not appeared publicly. Prior to the war, Iran was already experiencing internal unrest, with protests demanding economic reforms and greater political openness. The killing of Khamenei, while potentially creating a martyr figure, may also exacerbate existing tensions and lead to further instability.

Military Interdependence and the Cost of Conflict

The conflict has highlighted the interconnectedness of military alliances in the region. US military bases in several Gulf states, as well as NATO facilities in Cyprus and Türkiye, have become targets of Iranian missiles. Six US servicemen and a French peacekeeper have already been killed, demonstrating the human cost of the escalating conflict.
