Escalation analysis, alliance structures, and historical parallels
The question dominating global discourse on February 28, 2026 is whether the Iran-US-Israel conflict represents the beginning of World War 3. By the strict definition of a world war — direct military conflict between major global powers across multiple continents — the answer is currently no. The conflict remains primarily between the US-Israel coalition and Iran, confined (militarily) to the Middle East and Persian Gulf. However, the speed and scale of escalation are unprecedented in the post-Cold War era: six countries have been hit by missiles in a single day, multiple alliance structures are being tested, and the world's most critical energy chokepoint is under direct threat.
The alliance structures surrounding this conflict are what make it genuinely dangerous. Iran is a strategic partner of Russia and China, both of which have defence cooperation agreements with Tehran. Russia has supplied Iran with advanced air defence systems and has military advisors in the country. China imports roughly 1.5 million barrels of Iranian oil per day and has invested heavily in Iranian infrastructure under the Belt and Road Initiative. On the other side, the US has mutual defence treaties with Gulf states hosting its military bases, NATO Article 5 commitments, and ironclad security guarantees to Israel. If any of these alliance commitments are triggered, the conflict could expand rapidly.
Historical parallels are instructive but imperfect. The 1914 assassination of Archduke Franz Ferdinand showed how alliance obligations can drag powers into conflicts they never intended to fight. The 1962 Cuban Missile Crisis demonstrated that nuclear-armed states can come to the brink without crossing it — but only through deliberate back-channel communication. The current crisis has elements of both: interconnected alliance commitments and nuclear overtones, but also direct communication channels and mutual awareness of the stakes. The next 72 hours are critical in determining whether this conflict remains contained or spirals toward a broader conflagration.
Yemen's Houthi movement declared readiness to support Iran in any escalation, announcing they stand ready for 'any necessary development' in the conflict with the United States and Israel.
Iran's IRGC released footage claiming successful missile strikes on four major US military installations: Al Udeid Air Base (Qatar), Al Salem (Kuwait), Al Dhafra (UAE), and the US Fifth Fleet headquarters in Bahrain.
Major US police departments including NYPD, LAPD, Chicago PD, and Miami PD reported heightened security measures with increased patrols around synagogues and government facilities nationwide.
Tehran residents rushed to supermarkets as bread and water shortages emerged. Long queues formed at gas stations. Iran announced schools and universities closed, government operating at 50% capacity.
Etihad Airways announced suspension of all departures and arrivals until 14:00 UAE time on March 1, joining Emirates and other carriers in grounding operations.
Exiled Iranian Crown Prince Reza Pahlavi called on the Iranian military to defect and join the people, saying the strikes present an opportunity for regime change.
Ukrainian President Volodymyr Zelenskyy expressed support for the strikes against Iran, calling Tehran an accomplice of Russian President Putin in the war against Ukraine.
France, Germany, and the United Kingdom issued a joint statement distancing themselves from the US-Israeli military operation against Iran, stating they did not participate in the strikes.
An Iranian drone struck Kuwait International Airport, damaging the terminal building and injuring several workers. Kuwait closed its airspace and activated all defense systems.
The world's tallest building was evacuated as a precautionary measure during Iran's retaliatory missile strikes on the UAE. Dubai Civil Defence deployed teams across Saadiyat Island, Khalifa City, Bani Yas, MBZ City, and Al Falah.
Missile debris struck a hotel on Dubai's Palm Jumeirah island, killing one Pakistani national and injuring four others. Dubai Civil Defence controlled the resulting fire and deployed to multiple sites.
Satellite imagery reveals direct damage to Ayatollah Khamenei's compound in Tehran. Iran's Foreign Minister confirms both Khamenei and President Pezeshkian remain alive following the strikes.
By strict definition, no. World War 3 would require direct military conflict between major global powers on multiple continents. The current conflict primarily involves the US and Israel against Iran, with regional spillover across the Gulf. However, the involvement of multiple countries, the scale of missile exchanges, and the risk of great-power entanglement make this the closest the world has come to a global conflict since the Cold War. The situation remains volatile and could escalate further.
Russia and China have condemned the strikes and provided diplomatic support to Iran at the UN Security Council. Russia has significant military cooperation with Iran including weapons sales, while China is a major buyer of Iranian oil. However, neither has signalled intent to intervene militarily. Russia is still engaged in Ukraine, and China's focus remains on Taiwan and economic stability. Both may increase covert support — intelligence sharing, weapons transfers — without direct confrontation with the US.
The Iran strikes are most comparable to the opening of the 2003 Iraq War in terms of scale and the use of precision air campaigns, but with critical differences. Iran is a far more capable military adversary than Iraq was, possessing advanced ballistic missiles and an extensive proxy network. The regional spillover — with missile strikes hitting six countries in a single day — exceeds anything seen in the Iraq or Afghanistan conflicts. The 1962 Cuban Missile Crisis is a closer parallel in terms of great-power escalation risk.
Full escalation could involve: Iran closing the Strait of Hormuz, triggering a global energy crisis; Hezbollah launching a massive rocket campaign against Israel from Lebanon; Houthi forces intensifying attacks on Red Sea shipping; Iranian-backed militias attacking US bases across Iraq and Syria; and potential direct confrontation between US and Russian naval forces if Russia moves to resupply Iran. The worst-case scenario involves a ground campaign or the use of tactical nuclear weapons, though both remain highly unlikely.
