Location: Primary strikes across Iran (Tehran, Isfahan, Qom, Tabriz). Retaliatory strikes across Israel, Iraq, Bahrain, UAE, Qatar, and Jordan.

Started: February 28, 2026 (Ongoing).

Main actors:

  • The Iranian State :(IRGC, armed forces, political leadership)

  • United States :(policy + military)

  • Israel :(IDF + political leadership)

What is happening: On February 28, the United States and Israel launched a large-scale joint military operation described as Operation Epic Fury (also referred to as Roaring Lion). The strikes targeted military, nuclear, and leadership sites across Iran. The operation resulted in the killing of Iran’s Supreme Leader, Ali Khamenei.In response, Iran announced Operation True Promise IV, launching hundreds of missiles and drones targeting U.S. bases and allied infrastructure across the region. Iranian officials have also signaled the possibility of disrupting maritime traffic through the Strait of Hormuz.The conflict remains active, with exchanges continuing across multiple fronts.

Why it started:

The escalation followed the collapse of high-level negotiations in Geneva in February 2026. U.S. officials stated that Iran had reached a critical nuclear threshold, arguing that military action was necessary to prevent an imminent weapons breakthrough.The current approach reflects a renewed “Maximum Pressure” strategy aimed at weakening Iran’s governing structure. Israel has framed its participation as a pre-emptive security measure, citing concerns over Iran’s expanding missile capabilities and regional military posture.Iran rejects these justifications, describing the strikes as violations of sovereignty and acts of aggression.

What’s at stake:

  • Human Life and Regional Insecurity:

    Initial reports indicate significant casualties, including civilians affected by urban strikes. Retaliatory attacks across the region have heightened insecurity, affecting multiple states and civilian populations.

  • Regional Stability: The removal of Iran’s central leadership structure may create uncertainty within the country’s military and political institutions, raising concerns about fragmentation or expanded regional confrontation.The participation of allied and proxy actors is also evident in this conflict, including Hezbollah (Lebanon), the Houthis (Yemen), various Iraqi and Syrian militias, as well as Gulf state defense and diplomatic actors, further expanding the regional scope and complexity of the confrontation.

  • Global Economy: Potential disruption of the Strait of Hormuz, (a critical global energy transit route) could affect oil markets and contribute to inflationary pressures worldwide, particularly in energy-importing developing economies.

  • International Law: The targeted killing of a sitting head of state raises broader legal and diplomatic questions regarding sovereignty, pre-emptive force, and the application of international norms.

Why it matters now: This escalation marks a significant shift in regional dynamics, expanding confrontation beyond isolated strikes into a multi-state conflict zone. The situation carries implications not only for Middle Eastern security but also for global economic stability and the credibility of international legal frameworks.As events unfolds, the humanitarian consequences and regional spillover effects will likey shape both diplomatic responses and long-term geopolitical alignments.
