US midterm outcomes could reshape policy on Iran, Gaza and Ukraine

Democrats secured majorities in both the House and the Senate in the recent midterm elections, while Republicans lost control of both chambers. The new Democratic majority will take office in January, but it does not hold the two-thirds vote needed to override a presidential veto.

President Donald Trump, who has led the United States since January 2025, said the February strike on Iran raised gasoline prices briefly but called the action “the only answer” to prevent Iran from acquiring a nuclear weapon. He also indicated he will use his veto power to block any legislation he deems “insane.”

Senator Chuck Schumer said Democrats intend to end the war with Iran, citing congressional control of the budget as a tool to restrain a president who initiates conflict without broad public support. However, experts noted that cutting funding could be difficult while U.S. troops remain deployed, and that the War Powers Resolution is unlikely to limit the president’s authority without a supermajority.

In the Gaza arena, newly elected progressive Democrats have voiced criticism of Israel’s military campaign and pledged to push for a reduction in U.S. aid. Senator Abdul El-Sayed, who won a Senate seat for Michigan, said he will work to end U.S. assistance to Israel. President Trump claimed that Israeli Prime Minister Benjamin Netanyahu suggested ending the United States’ $4 billion annual aid package, though the Israeli office did not comment.

Regarding Ukraine, President Trump has repeatedly questioned U.S. support, suspended sanctions on Russian oil and delayed weapons deliveries. Ukrainian President Volodymyr Zelenskyy told German broadcaster ZDF that Democrats “speak very clearly about supporting Ukraine,” expressing hope for increased assistance once the new Congress convenes.

Analysts caution that while a Democratic Congress may favor stronger backing for Ukraine and a more restrained approach toward Iran, the lack of a veto-override supermajority could limit its ability to enact decisive policy changes.
