US voters have given a severe jolt to President Trump. Democrats swept both the House and the Senate in last week’s midterm elections, shifting the balance of power in Congress for the final two years of Donald Trump’s term.
The Iran war, which began in February, was central to the result. Nearly all voters, who backed Democrats in House races, called going to war the wrong decision, while roughly 8 in 10 Republican voters called it right. The White House acknowledged the truth. Trump said it was “probably true” that the war, and the gasoline prices that came with it, cost Republicans heavily. Vice President JD Vance was blunter, saying the party lost because of the war.
Democrats cannot act until they are sworn in. Analysts say Congress is unlikely to pass a war powers resolution before January, and Trump could veto one anyway. That leaves a lame-duck window of roughly two months in which the president has a free hand. He has not used it to retreat. The day after the election, Trump said “the Iran thing we had to do, and we will continue to do it.” He also said he would decide soon whether to attack Iran again, and repeated that Tehran will never have a nuclear weapon. Before the vote, Netanyahu reportedly pressed Trump to strike immediately after the election. Trump told the Financial Times on election night that he had no immediate plans to order attacks.
Congress has leverage, but not a veto-proof majority. Democrats have three main tools. They can pass a war powers resolution, launch investigations, or insert language into the defence budget barring funds for hostilities against Iran. The funding route is the strongest, since a president cannot veto Congress’s refusal to pass a bill. The war powers route is harder. A Senate war-powers vote failed by a single vote in September, while the House passed its own resolution 220–204. Overriding a veto would still need substantial Republican support.
Analysts disagree on the likely future course of action by Trump. The restraint case rests on the political damage Trump has suffered. Trump wants to protect his legacy and his party’s finances, and oil prices fell sharply on hopes that the results would push him toward a deal. Brookings scholar Robert Kagan told CNBC that Trump will probably leave Iran alone.
The escalation case rests on his mercurial temperament and the calendar. One analyst called him an attention seeker without a consistent long-term strategy, who may be even more eager to pursue dangerous adventures. Another review noted that lame-duck presidents historically tend to do more abroad, not less. Iran is also not helping him de-escalate. Supreme Leader Mojtaba Khamenei said the American collapse has accelerated. Fresh tanker fires in the Strait of Hormuz have raised fears of renewed confrontation. The likeliest outcome is neither a clean retreat nor an all-out campaign, but a limited, short strike, or continued pressure with talks running in parallel. That is an assessment, not a prediction, and the president has contradicted himself on this before.
The Gulf monarchies never wanted this war. According to media reports, Gulf officials in their recent meeting in Bahrain were worried about renewed war, even as they regard Iran as their top security threat. In Saudi Arabia, events have been cancelled and offices closed after intensified Houthi strikes. The Wall Street Journal reported that Washington warned Gulf governments of a short but intense campaign after the vote. For the Gulf, a Democratic Congress offers hope of restraint. A lame-duck Trump offers the opposite. Qatar and Saudi Arabia, meanwhile, are pursuing diplomacy. The conflict has also pushed Gulf states to reassess their defence partnerships with the United States.
Mainstream media coverage in the US has framed the result as a verdict on the war. The Conversation called the war deeply unpopular and costly. Time reported that Democratic leader Hakeem Jeffries urged Trump to end the war before the new Congress convenes. Columnists have been sharper. The Philadelphia Inquirer called a post-election bombing plan “dangerous and foolish.” Pro-Israel and conservative outlets stress the nuclear threat and argue that timing strikes after the election was a sound way to manage the risks. .
For Iran, the election results came as welcome news. Parliament Speaker Mohammad Bagher Ghalibaf, the chief negotiator, wrote that Americans said “NO TO WAR.” He also warned that any betrayal of that message would bring Washington a “Nightmare.” Russia reacted with cautious hope. Kremlin spokesman Dmitry Peskov said Moscow hoped the results would not affect Trump’s “peacemaking efforts.” A Russian commentator predicted that Trump’s wrath would now fall on Europe. Chinese Foreign Ministry spokesperson Mao Ning called the elections a domestic affair and said Beijing would keep working toward a “constructive strategic relationship.”
Europe has been largely quiet. There was no official reaction from leaders in Britain, France, Germany or Italy, though some officials in Brussels celebrated. European Parliament Vice President Christel Schaldemose said she was “cautiously optimistic.” Several analysts argued that Europeans should largely ignore the midterms, since Washington would pull back regardless of who holds power. The election has come as a big rebuff to Trump, but it is not yet clear whether he will be constrained. Until January, the decision on Iran is largely his, and he has said he will make it soon. After January, Congress can use its budget powers to restrain him.
