From allies to adversaries: War erupts between Israel, the United States and Iran

On 28 February 2026, hostilities officially erupted between Israel, the United States and the Islamic Republic of Iran, a development that starkly contrasts with the previous decades in which the three states, despite divergent regional ambitions, maintained a surprisingly pragmatic, if limited, framework of diplomatic engagement, intelligence sharing and occasional economic interaction. The immediate international reaction, characterized by muted condemnations and a conspicuous absence of decisive mediation effort from traditional regional bodies, further accentuated the vacuum left by a United Nations Security Council hamstrung by veto politics, thereby allowing the nascent war to progress with minimal external restraint.

The swift transition from diplomatic overtures to armed confrontation was precipitated by a series of mutually assured provocations, including alleged cyber intrusions attributed to Iranian actors, retaliatory airstrikes claimed by Israeli forces, and an increasingly vocal American pledge of unconditional support for Israeli security, all of which exposed the inadequacy of existing crisis‑management mechanisms and highlighted a collective inability to restrain escalation despite multiple back‑channel attempts at de‑escalation. Moreover, the United States' decision to integrate Iranian assets into its sanction regime shortly before the outbreak, without securing coordinated multilateral endorsement, effectively eliminated a potential diplomatic lever and signaled a unilateral escalation strategy that left Israel to shoulder the operational burden of confronting a well‑armed adversary on multiple fronts.

In the aftermath, casualties and material losses have been reported on all sides, while the abrupt abandonment of erstwhile cooperation underscores a systemic weakness within international security architectures that routinely prioritize short‑term political posturing over the establishment of durable preventive institutions, rendering the current conflict a foreseeable, if lamentable, consequence of chronic diplomatic neglect. Consequently, the conflict not only illustrates the fragility of erstwhile alliances but also serves as a cautionary exemplar of how institutional inertia and procedural opacity can convert diplomatic drift into open warfare, suggesting that without substantive reform the pattern of turning friends into foes may recur with predictable regularity.
