Democrats secured a significant victory in the recent US midterm elections, raising global attention on how the incoming Congress will approach ongoing conflicts in Iran, Gaza, and Ukraine. The election results, largely seen as a referendum on President Donald Trump's policies, particularly his decision to initiate a war with Iran in February, suggest a potential shift in American foreign policy.

The war in Iran has proven unpopular domestically, contributing to soaring fuel prices due to the closure of the Strait of Hormuz and costing US taxpayers an estimated $47 billion. This sentiment has led some prominent Republicans, including Vice President JD Vance, to distance themselves from the conflict.

European leaders expressed cautious optimism, hoping that the Democrat-controlled Congress, set to take office in January, will help repair transatlantic relations and potentially restore waning US support for Ukraine. President Trump has previously withdrawn support for Ukraine, citing strikes on Russian oil facilities for the fuel crisis and calling for the resignation of President Volodymyr Zelenskyy.

Democrats have largely opposed the US war on Iran since its inception, contrasting with the Trump administration's stance. Furthermore, a new wave of progressive Democrats elected in the midterms has voiced strong opposition to the conflict in Gaza and the actions of Israeli settlers in the occupied West Bank, a departure from the previous Biden administration's approach.

President Trump has vowed to use his veto power to counter any "insane" policies from the incoming Democratic majority, highlighting the potential for legislative gridlock. Overturning a presidential veto requires a two-thirds majority in both the House and the Senate, a threshold Democrats may struggle to achieve despite their wins.

The implications for the conflict with Iran are significant. While Democrats have opposed the war, their ability to immediately alter the course of military action will be constrained by the presidential veto. However, their increased influence in Congress could lead to greater scrutiny of the war's costs and objectives, and potentially shape future US policy.

Regarding Ukraine, the election results offer a glimmer of hope for President Zelenskyy. A Democrat-led Congress may be more inclined to resume or increase US aid, which had been curtailed by the Trump administration. This could provide crucial support to Ukraine as it continues to resist Russia's invasion.

The situation in Gaza presents a complex challenge. While progressive Democrats have been vocal critics of Israeli actions, the Biden administration's past policies have shown a reluctance to exert significant pressure. The new Democratic majority will face pressure to reconcile these differing views and determine a unified US approach towards the Israeli-Palestinian conflict.

Unresolved questions remain about the extent to which Democrats can translate their electoral gains into tangible policy changes, especially in the face of potential presidential vetoes. The coming months will reveal whether the midterm results signal a genuine shift in US foreign policy priorities concerning these critical global conflicts.
