Electoral Defeat and Lame Duck Status
The loss of Republican Party majorities in both the U.S. Senate and House of Representatives during the 2026 midterm elections has left President Donald Trump with diminished legislative power for the remainder of his tenure. According to Oilprice, Democrats taking control of both chambers has effectively ended Trump’s ability to dictate domestic policy through legislation.
Trump acknowledged that the ongoing war with Iran was "largely true" in causing the Republican loss of both houses of Congress. Despite this admission, he stated he had no regrets and would "do it again," arguing that preventing Iran from acquiring a nuclear weapon justified the electoral losses.
Lara Trump told journalists that her father-in-law realized the Iran war could cost him the elections but insisted losing both chambers of Congress would be worth the cost to prevent Iran from obtaining a nuclear weapon. The political fallout was reflected in financial markets, with headlines indicating oil prices plunged below $92 as Trump signaled restraint on Iran. Prices crashed 9% as Trump and Vice President Vance blamed the Iran war for the midterm rout.
Unilateral Authority Over Foreign Affairs
While domestic legislative power has evaporated, Oilprice reports that Trump retains unilateral legal authority to escalate or de-escalate military pressure abroad. This includes significant discretion regarding the ongoing war with Iran. Furthermore, he maintains the right to dictate terms of U.S. alliances and treaties, such as those related to the Russia-Ukraine War, without needing congressional approval.
This executive independence extends to economic policy as well. Trump can implement or increase economic tariffs unilaterally, bypassing the legislative gridlock that has paralyzed his domestic agenda. The contrast between his constrained domestic position and expansive foreign powers creates a unique dynamic for the remainder of his presidency.
Origins and Objectives of the Iran Conflict
The context for these unilateral actions is rooted in the conflict launched as ‘Operation Epic Fury’ on 28 February. Endorsed by Trump’s entire cabinet, the operation had four original objectives: making it impossible for Iran to build a nuclear arsenal; degrading and destroying its missile stockpiles and production capabilities; effecting regime change; and ending the financing and arming of Iran’s proxies.
Trump’s personal stance on the conflict is influenced by historical grievances. He believes Iran is to blame for his electoral loss and has a documented dislike of losing or losers. This perspective references his view that former President Jimmy Carter’s weakness in dealing with Iran during the 1979 hostage crisis emboldened Iranians and led to Carter’s re-election defeat.
Strategic Calculations for 2028
Beyond immediate policy goals, Trump’s actions are driven by long-term political survival. He aims to prevent Republicans from losing the 2028 presidential elections. His objective is to ensure a sympathetic government that can block Democratic censure or impeachment moves against him.
International markets have reacted to these geopolitical shifts. European gas prices dropped on hopes of an Iran deal following the U.S. midterms. Additionally, Iraq struck a U.S. deal to boost oil exports through the Hormuz strait, signaling ongoing diplomatic and economic maneuvering despite the domestic political turmoil in Washington.
