Contrary to prevailing forecasts and expert expectations, the conflict in and around Iran remains active and continues to escalate. What was initially regarded as a localized confrontation has evolved into a broader regional war, carrying potentially severe consequences across political, economic, and humanitarian dimensions. States within the region are increasingly compelled to adapt to a rapidly shifting reality, where Iran’s military operations directly influence both domestic and foreign policy decisions, while also impacting global energy flows and international trade. The protracted and multi-actor nature of the conflict has proven highly unpredictable, defying even the most sophisticated analyses.

Iran’s resilience, despite strict international sanctions and diplomatic isolation, has emerged as a central challenge. The country has consistently withstood repeated military strikes while simultaneously mounting its own offensive measures. This unexpected endurance has disrupted initial U.S. and allied assumptions, which anticipated rapid pressure on Tehran sufficient to resolve the conflict swiftly. As a result, states are forced to develop flexible strategies to manage both the direct and indirect consequences of the war, encompassing political maneuvers as well as economic instruments. This adaptation underscores the necessity of revisiting established regional engagement frameworks.

The ongoing conflict has also intensified domestic political divisions in the United States. Both Democrats and Republicans are engaged in intense intra-governmental and electoral competition, affecting the coherence of U.S. foreign policy. Congress and the executive branch are divided on key issues such as defense budget allocations, sanctions policy, and strategic initiatives in the region, complicating the formation of a unified national position on international affairs. With elections approaching, the political stakes are particularly high: prolonged hostilities and perceptions of administrative ineffectiveness may undermine President Donald Trump’s standing, offering Democrats a potential advantage in framing themselves as pragmatic and responsible actors on the world stage.

Support among Republicans for Trump remains substantial. A recent Quinnipiac University poll found that 86% of Republicans support U.S. military operations in Iran, with 80% approving of the president’s management of these actions. In contrast, Democrats largely oppose nearly all of Trump’s initiatives since his return to office, and independent voters appear increasingly skeptical. A key point of Democratic criticism concerns the financial burden of the conflict for U.S. taxpayers, particularly given the lack of a direct national interest in engaging with a distant adversary. Estimates from the Center for Strategic and International Studies indicate that expenditures reached $12.7 billion in the first six days of operations, likely exceeding $18 billion to date, with costs continuing to rise. The lack of clear cost transparency from the White House, alongside contradictory guidance from the Pentagon and U.S. Central Command, has further fueled public and legislative concern.

The administration’s early reliance on high-cost, high-technology weaponry—long-range missiles, missile interceptors, and radar systems—quickly depleted stockpiles, diminishing U.S. strategic depth. Although subsequent operations have relied on less expensive, shorter-range weapons, the initial resource expenditure imposed a significant financial burden on American taxpayers. Senator Elizabeth Warren highlighted the tangible domestic consequences, including increased household expenses due to higher gasoline and heating costs, which have risen more than 10% and continue to escalate.

Legislative scrutiny has mirrored public unease. Lawmakers attending closed briefings on Iran have questioned both the objectives and efficacy of military operations. Senator Chris Murphy characterized U.S. and Israeli strikes as “inconsistent and incomplete,” noting that briefings are conducted behind closed doors because the administration cannot publicly justify its actions. Congressional divisions are further reflected in repeated attempts by Democrats to limit presidential authority over military engagement. The Senate recently rejected a resolution that would have prohibited Trump from conducting military operations without Congressional approval, with only 47 in favor and 53 opposed. This marked the second attempt within a year to constrain the president following attacks on Iranian nuclear sites in mid-2025.

Economic and energy concerns form a second pillar of Democratic criticism. In the weeks following the outbreak of conflict, the vulnerability of the U.S. economy to energy price shocks became apparent. According to Ipsos, public approval of Trump’s economic policies fell from 43% at the start of his second term to 35% by June 23, 2025. Within three weeks of hostilities, gasoline prices rose to nearly $4 per gallon, prompting protests in several states and serving as a visible indicator of the domestic cost of geopolitical risk.

Global energy market disruptions have exacerbated the problem. Oil supplies dropped by nearly 20 million barrels per day, commercial inventories fell sharply, and reserves reached critically low levels. Brent crude prices surged to $190 per barrel in August, surpassing the 2008 record of $147. Prices for diesel, jet fuel, and marine fuel rose even further, while European and Asian natural gas prices reached $30/MMBtu in the third quarter, increasing electricity costs and complicating winter energy preparations. Domestic energy dependence, coupled with international supply disruptions and regional infrastructure damage, magnifies the economic consequences of the conflict.

The Trump administration sought to mitigate domestic political fallout by pressing Gulf states to offset some U.S. operational costs. Yet these countries have already incurred losses of roughly 1% of their GDP and insist that Iran should bear responsibility. Iranian authorities, in turn, refuse to provide compensation and anticipate reparations from their adversaries. Disruptions at key industrial facilities, such as ExxonMobil’s plant in Ras Laffan, combined with halted production and missile damage, have reverberated across global supply chains. Additionally, long-term reductions in shale oil output limit the ability to rapidly increase domestic production. As Oxford Economics warns, sustained oil prices of $140 per barrel could push the U.S. economy toward contraction.

Domestic political dynamics are further complicated by internal divisions within the Republican Party. The number of Republicans skeptical of military engagement has grown, reflecting a split within the MAGA movement led by Trump. The movement now comprises two factions: an anti-war, isolationist wing, led by figures such as commentator Tucker Carlson, former Congresswoman Marjorie Taylor Greene, and Senator Rand Paul, which prioritizes domestic policy; and a hawkish faction, loyal to Trump, advocating assertive foreign policy and military action to maintain U.S. global influence.

This intra-party division extends to succession planning, with potential rivals such as Vice President J.D. Vance and Secretary of State Marco Rubio representing the anti-interventionist and hawkish wings, respectively. The Iran conflict has amplified these tensions, making the Republican Party’s future direction uncertain.

Even if hostilities with Iran conclude, Trump faces a challenging electoral landscape: declining approval ratings and internal party divisions persist. For Democrats, careful selection of both strategy and candidate will be crucial to leverage these political and economic pressures in the upcoming elections.
