The U.S. strike on Iran did not generate “national unity” in Washington; on the contrary, it reignited a fierce debate over whether Trump can exercise war powers without congressional authorization. Objections not only from Democrats but also from some Republicans indicate that the operation has evolved into a domestic legitimacy crisis. Along the UN track, it has been emphasized that the attack lacks either a Security Council mandate or a clear self-defense basis under Article 51. Trump’s assumption that “eliminating the leader will unravel the regime” could backfire given Iran’s institutional structure, potentially strengthening security-oriented consolidation. Polls show that the public does not strongly support this military step, and X has emerged as a space where anti-war voices from both the right and left converge.

The U.S. strike on Iran did not produce the expected image of “national unity” in Washington. On the contrary, from the very first hours, the operation triggered sharp debate on both legal and political grounds. At the center of the discussion lies the question of whether Trump can order such an operation without congressional approval.
In Congress, Democrats in particular argue that the strike was not based on an “imminent and unavoidable threat” and therefore exceeded presidential authority. Notably, some Republicans have joined these criticisms. Republican factions long opposed to foreign interventions have openly stated that the operation contradicts Trump’s past “America First” rhetoric.
This limited but symbolically significant dissent within the Republican Party has further expanded the debate in Washington. Figures such as Thomas Massie, Rand Paul, and Warren Davidson have broken with the White House line, insisting that congressional authorization for war is mandatory. Meanwhile, party leadership and the hawkish wing continue to support Trump’s decision, defending a hardline policy toward the Iranian regime as necessary. The issue has thus turned into an internal direction debate within the Republican Party itself.
At the same time, many members of Congress state that they were not given a comprehensive briefing before the operation and that the legal justification was not clearly presented. The fact that only a limited number of senior congressional leaders received a brief notification has fueled criticism that the legislative branch was deliberately sidelined. This situation is being interpreted as an “institutional reaction” against the steadily expanding room for executive maneuver in foreign policy in recent years.
Votes planned in the coming days will test efforts to limit the president’s war powers. Whatever the outcome, the mere fact that such an initiative has materialized in Congress is being viewed as a serious political warning to the White House. Some commentators have begun to see this process as a historical threshold comparable to the 2002 authorization vote for the Iraq War.
The strike has also brought serious legitimacy debates under international law. Under the United Nations system, the use of force by one state against another is legally justified only in two circumstances: either there is explicit authorization by the UN Security Council, or the action falls under Article 51 of the UN Charter as self-defense against an armed attack. Outside these two exceptions, the use of force conflicts with the fundamental principles of sovereign equality and the prohibition of force.
In the current case, there is no Security Council authorization for the strike, nor has a universally accepted legal framework been presented demonstrating that it was a necessary act of self-defense against an urgent and unavoidable threat.
Indeed, UN Secretary-General António Guterres, addressing the Security Council, stated that everything must be done to prevent escalation. Otherwise, he warned of “a wider conflict that could have grave consequences for civilians and regional stability.” While stating that U.S. and Israeli airstrikes violated international law, including the UN Charter, Guterres also condemned Iran’s retaliatory attacks, noting violations of the sovereignty and territorial integrity of Bahrain, Iraq, Jordan, Kuwait, Qatar, Saudi Arabia, and the United Arab Emirates.
On X, Donald Trump announced that Ayatollah Ali Khamenei had been killed, describing it as “justice.” He called on the Iranian people to “take back your country” and implied that members of Iran’s military and security forces could be forgiven if they switched sides rather than resisted. The tone of the statement amounted to an open call for regime change. Trump framed the development as a historic opportunity for Iran and emphasized that operations would continue.
This rhetoric is based on the assumption that removing the leader will automatically lead to regime collapse. However, the functioning of modern states—particularly security-based and ideologically structured systems—is not so simple. Iran’s political system possesses core pillars that ensure continuity, including constitutional succession mechanisms, religious institutions, the Revolutionary Guards, and a multilayered security bureaucracy. Therefore, the loss of a leader may produce not systemic collapse but renewed consolidation.
Moreover, external intervention or explicit calls for regime change from abroad may strengthen rather than weaken internal mobilization. The Iranian regime’s long-standing narrative of “external siege” appears confirmed by such developments. This could empower security hardliners domestically while narrowing the space for reformists and opposition actors.
Even where anti-regime sentiments exist, for them to evolve into sustainable revolutionary transformation, factors such as fragmentation within the security apparatus, elite divisions, and an organized alternative leadership are required.
Trump’s statement on X, grounded in the assumption that eliminating the leader will directly produce regime change, simplifies Iran’s institutional structure and social dynamics. The real question is not whether the system will collapse, but whether such a shock will push Iran toward a more radical, more pragmatic, or more security-centered trajectory.
On the other hand, this strike is likely to have significant near-term consequences in U.S. domestic politics. Polling data clearly show that the American public does not strongly support this military action.
According to a University of Maryland poll, 49 percent of Americans oppose such an intervention, while 30 percent say they are undecided. In other words, a large majority of the public is either openly against the strike or not persuaded to support it.
Even among Republican voters, serious reservations are evident. The poll shows that 40 percent of Republicans support an attack, 25 percent oppose it, and 35 percent express no clear opinion.
An AP-NORC poll conducted last week likewise revealed low confidence in President Trump’s ability to make the right decisions regarding the use of military force abroad. Only 27 percent of Americans said they trust him to make correct choices on this issue, and among political independents that figure falls to just 14 percent.
Meanwhile, newly released Gallup data indicate that support for Israel in the United States has fallen to one of its lowest levels in decades. Forty-one percent of respondents now say they sympathize more with Palestinians, while 36 percent feel closer to Israelis. This represents a marked shift from the pre-October 2023 balance, when 54 percent favored Israel and 31 percent favored Palestinians. Over the past two years, a historic break in public sentiment appears to have occurred.
Although partisan divides persist, the most striking shift is among independents. Democratic voters, who had already moved toward greater sympathy for Palestinians since 2023, have largely maintained that position, while independents have, for the first time, shown a similar tendency. Support for Israel remains strong among Republicans but has dropped by roughly 10 points compared to 2024, reaching its lowest level in two decades. The Israel issue is thus no longer an uncontested area of consensus in U.S. domestic politics.
The generational divide is even more pronounced. For the first time since Gallup began tracking this question in 2001, a majority of Americans aged 18–34 say they sympathize more with Palestinians. Among younger respondents, support for Israel fell from 45 percent to 28 percent within a single year—a record decline. While older generations remain relatively more supportive of Israel, erosion is visible there as well. At the same time, around 60 percent of Americans continue to support the creation of an independent Palestinian state, a figure that has remained relatively stable in recent years.
In this context, it can be argued that events such as the Epstein scandal have contributed to a broader climate of distrust, particularly among younger and independent voters, fostering increased scrutiny of traditional support for Israel.
Finally, Elon Musk’s X platform must be mentioned in this process. X has become a space where anti-war opposition from different ideological currents gains simultaneous visibility. The platform enables traditional Democratic anti-war circles to amplify their voices, while also giving prominence to influential figures on the American right, such as Tucker Carlson and Alex Jones, who similarly advance anti-intervention arguments.
Thus, X has created a communication arena that blurs the conventional right–left divide. Actors who would traditionally remain distant from one another intersect in the same digital public sphere in opposition to military intervention in Iran. This development indicates that the issue is evolving into a broader systemic legitimacy debate within U.S. domestic politics. X’s algorithmic visibility structure, combined with Musk’s emphasis on “free speech,” has functioned as a catalyst accelerating the simultaneous mobilization of this heterogeneous opposition.
