The most surprising aspect of the conflict, which began on February 28, 2026, is the speed and scale of the initial decapitation strike. In the first hours of Operation Epic Fury, a joint U.S. and Israeli attack destroyed the leadership compound in Tehran and killed Supreme Leader Ali Khamenei, along with several high-ranking military commanders. This immediate removal of the top tier of the Iranian government deviates from the typical escalatory patterns seen in previous Middle Eastern conflicts.
That the Iranian command structure appears to be in significant disarray is also unexpected. While Iran managed to launch retaliatory strikes against U.S. bases and neighboring Gulf states, the Israel Defense Forces note that these barrages are inconsistent. Iranian personnel are reportedly abandoning missile launchers after a single use or upon hearing drones. This suggests a breakdown in the symmetry and logic usually found in the Iranian military’s coordinated response.
The breadth of the geographical spillover has also caught many by surprise. Iran responded not just by targeting Israel and the United States, but by striking civilian infrastructure across the region. Airports and shipping ports in Kuwait, the United Arab Emirates, and Oman have been hit. Qatar even launched its own retaliatory strikes against Iran after an attack on Hamad International Airport, marking a rare instance of a Gulf state engaging in direct offensive operations against Tehran.
The domestic situation inside Iran adds another layer of unpredictability. A nationwide internet blackout restricts connectivity to one percent to prevent organized internal demonstrations. Despite this, some student protests continue. The interplay between the foreign military campaign and the weakened legitimacy of the regime creates an unstable environment where the eventual outcome of the stated goal of regime change remains unclear.
Many expected Iran’s response to focus primarily on US military bases and Israeli targets. Instead, Iran launched significant missile and drone strikes on civilian infrastructure, hotels, residences, and other sites in the UAE, Saudi Arabia, Qatar, Bahrain, Kuwait, Oman, and even reportedly causing minor damage to a US embassy in Riyadh. This shocked Gulf countries (which had been working toward de-escalation with Iran) and pulled them much more actively into condemning and potentially opposing Iran. President Trump himself called the scale of attacks on the Gulf “probably the biggest surprise” of the conflict so far, noting that these states “were going to be very little involved and now they insist on being involved.”
Rapid formation of a broader anti-Iran coalition — Gulf states (including Saudi Arabia, UAE, Bahrain, and others), Jordan, and several Western countries quickly condemned Iran by name and asserted self-defense rights, with little criticism of the initial US-Israeli strikes. This reversed years of Iranian diplomatic efforts to improve ties with Arab neighbors and created an unexpectedly unified front against Tehran.
Iran’s apparent tactical successes vs. strategic disarray — Iran has managed some missile penetrations (hitting parts of central Israel, including Tel Aviv areas) and maintained a steady (if lower-volume) barrage, but reports highlight severe internal issues: leadership disarray after the reported killing of Supreme Leader Ali Khamenei in the opening strikes, catastrophic IRGC command losses, ineffective air defenses over key areas like Tehran, and coordination problems in retaliatory attacks. Many expected stronger, more unified Iranian resistance given preparations since the 2025 exchanges.
Gulf states shifting “off the sidelines” — The decision by Iran to target Gulf civilian and economic sites (rather than limiting to military ones) has backfired by rallying Arab states against it, potentially opening the door for them to support or join strikes — a development analysts describe as one of the most noteworthy and unforeseen early outcomes.
Speed and visibility of Israeli/US strikes inside Iran — Strikes have hit high-profile regime sites in Tehran (including reported damage to nuclear facilities like Natanz, leadership compounds, and state broadcaster), with air superiority established quickly. This contrasts with more limited or remote-targeting expectations, and the regime appears far more vulnerable than anticipated despite prior warnings.
The supreme leader has been killed early in the conflict. The U.S.-Israel strikes that began in late February included the targeted killing of Ali Khamenei, Iran’s supreme leader, a move that breaks long-standing norms about avoiding decapitation of a major regional power’s highest figure. There is no clear historical precedent for such a decisive removal so early in a major conventional campaign.
Iran’s retaliation has hit Gulf states directly. Rather than confining its response to military targets or proxy strikes, Iran has launched missiles and drones not only at Israel and U.S. bases but also at neighboring Gulf countries including the UAE and Qatar. Targets have included civilian infrastructure like airports, hotels, and oil facilities, widening the war beyond the original belligerents. Gulf states that tried to remain neutral are being drawn in.
The war quickly spread along multiple fronts. The conflict has moved beyond Iran and Israel to include strikes on U.S. bases in several Gulf countries, Hezbollah in Lebanon firing into Israel, and Saudi Arabia formally protesting attacks on its territory. What started as strikes on Iranian targets is now a multi-actor, regional fight.
The Strait of Hormuz has effectively been closed. Iran’s actions and warnings around that chokepoint have led shipping to largely stop, disrupting roughly a fifth of the world’s oil trade and pushing global prices higher. That kind of economic shock so early in a war is rare and threatens global markets beyond the region.
The scale and form of Iranian missile use is notable. Iran appears to be using advanced systems, possibly including hypersonic missiles, in addition to large salvos of ballistic missiles across a broad geographic area, testing air defenses and signaling a shift in how regional powers employ their strategic arsenals.
There is no clear exit strategy. Senior U.S. officials publicly acknowledge the campaign could take much longer than initially projected, with mixed messaging about goals like regime change, missile capability degradation, or neutralization of threats. This uncertainty contrasts with the often-publicized, short-duration objectives typical of modern U.S. engagements.
