A Nation Divided: Anti-War Marches and Iranian Diaspora Celebrations Sweep Across America as U.S.-Israeli Strikes Kill Khamenei and Ignite a Widening Conflict

On the evening of February 28, 2026, the United States and Israel launched a coordinated military assault on Iran — codenamed Operation Epic Fury by the Pentagon and Operation Roaring Lion by the Israeli military — that would kill Iran's Supreme Leader Ali Khamenei, upend the Middle Eastern order, and send shockwaves rippling through American streets [1][2]. Within hours, two very different Americas took to those streets: one waving pre-revolutionary Iranian flags in jubilation, the other carrying "Hands Off Iran" banners in fury.

The result is a nation confronting not only the geopolitical consequences of the most significant U.S. military action since the 2003 invasion of Iraq but also a fractured domestic consensus over what this war means — and whether it should be happening at all.

The Strikes That Changed Everything

The joint operation began in the early hours of February 28, targeting Iranian nuclear facilities, missile production sites, IRGC command centers, and the personal compound of Ayatollah Ali Khamenei in Tehran [1][3]. Israel's military confirmed that top Iranian security officials were among those killed, including the country's defense minister, the commander of the Revolutionary Guard Corps, and the secretary of the Iranian Security Council [4].

The Fars News Agency, affiliated with the IRGC, reported that Khamenei's daughter, son-in-law, grandchild, and daughter-in-law were also killed in the strikes on his compound [4]. Iran's state media confirmed the Supreme Leader's death on March 1, and the state declared 40 days of mourning and a seven-day national holiday [5].

President Trump outlined four military objectives for Operation Epic Fury: preventing Iran from acquiring a nuclear weapon, destroying its missile arsenal and production sites, degrading its proxy networks, and annihilating its navy — alongside a stated political goal of regime change from within [6]. Trump framed the strikes as a counterproliferation measure and a direct consequence of Iran's refusal to renounce nuclear ambitions despite three rounds of negotiations [6].

By March 2, the death toll inside Iran had reached at least 555, according to the Red Crescent, with civilian casualties mounting [7]. One of the deadliest single incidents involved an Israeli strike on the Shajareh Tayyebeh girls' elementary school in Minab, in Iran's Hormozgan province, which killed 165 people — most of them children — and injured 96 others [8].

Two Americas Take to the Streets

The domestic response split along lines that defied conventional partisan boundaries.

Celebrations in the Diaspora

In Times Square, hundreds of Iranian-Americans waved pre-Islamic Revolution flags bearing the lion-and-sun emblem and chanted for Reza Pahlavi, the son of Iran's deposed shah. "Alternative for Iran, King Reza Pahlavi!" and "Khamenei is gone!" rang through the crowd [9]. In Portland, Oregon, a gathering at Pioneer Courthouse Square took on a party atmosphere. Bahar Behboodi, one of the organizers, told OPB that almost everyone present was born under the regime or had loved ones still living in Iran. "This is something that we've been asking for, begging for, crying for, for 47 years, and finally it's done," Behboodi said [10].

In Los Angeles — home to the largest Iranian diaspora community in the United States — people played Persian music, sang, wept, and celebrated. Demonstrators waved American and Israeli flags and carried signs reading "Thank you, Trump" [11].

For many in the diaspora, the strikes represented a cathartic moment — the destruction of a theocratic regime that had imprisoned, tortured, and executed political dissidents for decades. The 2025–2026 protest movement inside Iran, which had already seen significant internal unrest, provided an emotional backdrop [12].

The Anti-War Movement Mobilizes

Yet in many of the same cities, a parallel movement was forming. Hundreds of demonstrators gathered near the White House in Washington, D.C., on the night of February 28, condemning the strikes as illegal and a violation of international law [13]. The ANSWER Coalition (Act Now to Stop War and End Racism), American Muslims for Palestine, CodePink, the Democratic Socialists of America, the National Iranian American Council, the Black Alliance for Peace, and the youth-led 50501 movement organized rapid-response rallies [13][14].

In San Francisco, hundreds marched along Market Street in a "Hands Off Iran" rally, occupying the roadway while calling for an arms embargo and an end to U.S. involvement [15]. In Seattle, protesters gathered at Pike Place Market. In Chicago, approximately 100 people rallied at Federal Plaza. Actress Jane Fonda joined demonstrators at a Los Angeles rally [9][14].

By March 2, the ANSWER Coalition had called for nationwide mobilizations, with protests planned in dozens of additional cities [14]. The coalition framed the conflict as "Iraq 2.0" — a charge that found unlikely echo on the political right. Influencer Nick Fuentes wrote that the strikes were "literally Iraq 2.0" and that "the GOP has utterly and completely betrayed America First," while Andrew Tate also voiced opposition [9].

Congress Confronts Its Constitutional Crisis

The strikes were launched without congressional authorization, and members of Congress were left confronting a familiar but increasingly urgent reality: they had been informed of the operation but given no role in approving it [16][17].

In the Senate, a bipartisan war powers resolution led by Democratic Sen. Tim Kaine of Virginia and backed by Republican Sen. Rand Paul of Kentucky would require the president to obtain explicit congressional authorization before engaging in further hostilities against Iran [17]. In the House, Rep. Ro Khanna (D-CA) and Rep. Thomas Massie (R-KY) prepared a parallel bipartisan resolution [16].

The constitutional stakes are significant. Article I of the Constitution grants Congress — not the president — the power to declare war. Yet as TIME magazine noted, Congress is confronting its "limited power over war" in a situation where combat operations are already well underway [18]. The resolutions are widely expected to fall short of the two-thirds majority required to override an expected presidential veto, meaning they would function primarily as a political rebuke rather than an immediate constraint on military operations [17].

The Trump administration has cited documented attacks by Iran and its proxies on U.S. forces and allies as justification under the War Powers Resolution, which permits hostilities in response to "a national emergency created by attack upon the United States, its territories or possessions, or its armed forces" [6][19]. Legal scholars remain sharply divided on whether this threshold has been met.

The War Widens: Iran Strikes Back

The protests on American streets are unfolding against the backdrop of a rapidly escalating regional conflict. In retaliation for the strikes and Khamenei's assassination, Iran launched dozens of drones and ballistic missiles throughout the Persian Gulf, targeting Israel as well as U.S. military bases in Jordan, Kuwait, Bahrain, Qatar, Iraq, Saudi Arabia, and the United Arab Emirates [20][21].

Video footage showed Iranian missiles striking Beersheba, Israel [22]. The U.S. Embassy compound in Riyadh, Saudi Arabia was struck by drones, and at least six U.S. service members have been killed since the start of hostilities [23]. Iran also reportedly struck civilian aviation facilities, including international airports in Kuwait and the UAE [21].

The strikes on Gulf states sent shockwaves through cities like Doha, Manama, and Abu Dhabi, where stunned tourists and residents watched interceptor missiles fly overhead, with many fleeing [21]. In Pakistan, at least 10 people were killed and more than 70 wounded near the U.S. consulate in Karachi after pro-Iranian protesters attempted to storm the building and security forces opened fire [24]. In Baghdad, hundreds of Iraqis attempted to storm the compound housing the U.S. embassy [9]. Hezbollah fired rockets at northern Israel for the first time since the November 2024 ceasefire [25].

Trump warned Iran not to retaliate further, and stated that the operation could take "four weeks or less" [26][27]. Americans were urged to immediately leave more than a dozen countries in the Middle East [28].

The Deeper Fissure

What makes the American protest landscape so remarkable is not merely its scale but its ideological incoherence by traditional standards. The anti-war movement includes progressive Democrats, libertarian Republicans, and figures from the online populist right. The pro-strike celebrations include Iranian-Americans who span the political spectrum but are united by decades of personal suffering under the Islamic Republic.

The National Iranian American Council, a prominent advocacy group, has itself been divided — welcoming the end of Khamenei's rule while expressing alarm at the scale of civilian casualties and the prospect of prolonged war [11][14]. This mirrors a tension felt across much of the Iranian diaspora: relief at the toppling of a brutal theocracy, paired with horror at the human cost.

For the broader American public, the conflict raises questions that echo through generations of U.S. foreign policy. The stated objectives — counterproliferation, regime change, degradation of proxy networks — recall the language of Iraq in 2003, with all the unresolved trauma that comparison carries. The White House has explicitly framed the operation under its "Peace Through Strength" doctrine [6], but critics argue that a war initiated without congressional approval, without a serious public debate, and in the face of significant public opposition is neither peaceful nor strong [16].

What Comes Next

As the conflict enters its third day, an interim leadership council is expected to form in Iran, with the president, the head of the judiciary, and a jurist from the Guardian Council assuming responsibility until the election of a new supreme leader [4]. Whether this transition leads to the internal regime change Washington desires or a hardening of anti-American sentiment remains an open question.

On American streets, the protests show no sign of abating. The ANSWER Coalition has called for sustained mobilization. Iranian diaspora groups are planning continued demonstrations. And in Congress, the war powers vote — expected this week — will serve as the first formal legislative reckoning with a conflict that has already reshaped the Middle East and exposed the fault lines of American democracy itself [17][18].

The question now is not whether Americans are divided over this war. They are. The question is whether any of the institutions designed to channel that division — Congress, the courts, the press, the ballot box — can catch up to events that are moving faster than democracy itself.
