Deep American Divide Over Iran War: Trump Loses Broader Alliance Despite "MAGA" Base Solidity

News Analysis

Latest polls in the United States indicate a widespread decline in public support for the war on Iran, launched by President Donald Trump, with only a quarter of Americans considering it a "war worth fighting." With its economic cost continuing to rise, domestically and globally, this percentage is expected to decline further in the coming months.

Despite this sharp decline in popular support, Trump appears to be in a unique political position as a president at the end of his term, making him less susceptible to traditional pressures from Congress or even from public opinion. The war, and the accompanying economic inflation and rising energy prices, are likely to weaken the Republican Party in the midterm elections, but without the president facing a direct threat of impeachment or institutional rebellion.

However, the most important debate is not only about public opinion, but about the cohesion of Trump's political base itself. While the solid base of "MAGA" supporters remains committed to him, even with the war, prominent figures from the populist right have begun to declare their opposition, accusing the president of abandoning his electoral promises, foremost among them the slogan "America First."

The division within the Republican Party is no longer a simple one between supporters and opponents, but rather reflects a deeper rift within the alliance that brought Trump to power in 2024. While a part of the base shows almost absolute loyalty to the president, another part sees the war on Iran as a direct betrayal of promises to end the "endless wars" that have exhausted American society for a quarter of a century.

Poll data indicates that about 66% of Americans oppose the decision to go to war, while 68% oppose the use of ground forces in Iran. Also, 69% are concerned about its economic repercussions, especially on fuel prices, while 64% express their lack of confidence in the president's ability to manage the crisis. These numbers clearly reveal that about two-thirds of Americans stand against the continuation of the war.

But this general rejection is accompanied by a sharp partisan division. About 77% of Republicans support the war, and the percentage rises to about 90% among those classified as "MAGA" within the party. However, even within this category, Iran does not appear to be a political priority, as only 11% consider it a central issue, compared to a greater focus on inflation and domestic economic conditions.

In contrast, sharp divisions have emerged within the right-wing media itself. Trump entered into an open confrontation with prominent figures such as Tucker Carlson, who declared his feeling of "betrayal" and his rejection of the war, while the president responded by describing him and those who criticize the war as "losers" who do not represent the true MAGA movement.

However, this media conflict hides a broader reality: opponents of the war are not limited to media figures, but also include a wing within the Republican establishment itself. Some former officials resigned in protest, considering that the war contradicts the principle of "America First," and some even went so far as to accuse external influences, including Israeli pressures, of pushing the decision towards escalation.

Poll studies reveal that Trump's electoral base is not a single homogeneous bloc. Only about 30% of his voters are classified as "solid MAGA," while the rest form a fragile alliance of independent voters and voters dissatisfied with the Democratic Party. These latter categories are currently the most opposed to the war.

Divisions also appear based on age and education; young Republicans are about 30 points less supportive of the war compared to older people, and working-class voters without a college education have gradually begun to withdraw their support, especially with the deterioration of economic conditions.

In this context, it appears that the war in Iran has not only weakened the president's international image, but has begun to dismantle parts of the electoral alliance that brought him to the White House. Although the solid base remains cohesive, the broader margin of supporters shows a clear decline, raising questions about the future of this political alliance after Trump.

The war in Iran reveals a fundamental contradiction in Trump's political project between the slogan "America First" and the options of widespread military intervention. While his popularity was built on rejecting foreign wars, the military decision weakened trust between him and the base that joined him for economic and social reasons more than ideological ones. This shift reflects the fragility of the populist alliance, which coheres around personality more than around policies. With increasing economic costs, maintaining this balance becomes more difficult over time and as the effects of the war expand domestically.

The division within the Republican Party does not merely reflect a disagreement over foreign policy, but expresses a deeper struggle over the party's identity itself. There is a current that tends towards isolationism and avoiding military interventions, versus a more traditional current that leans towards hard power and foreign alliances. The Iran war ignited this contradiction in an unprecedented way, especially with media and populist voices entering into direct confrontation with the president. This division may have long-term repercussions that extend beyond Trump's term, reshaping Republican foreign policy for years to come.

Moreover, public opinion figures indicate a broader crisis of confidence in the American political establishment as a whole, not just in the Trump administration. The rejection of the war by two-thirds of Americans reflects societal exhaustion from repeated foreign interventions over the past decades. This popular mood places any future administration, Democratic or Republican, under strict constraints regarding the use of military force. The erosion of confidence in the executive leadership in crisis management also deepens the gap between citizens and decision-makers, making foreign policy more susceptible to internal fluctuations.
