US midterms: What changes for foreign policy—and what doesn’t

Democrats swept both chambers of Congress in Tuesday's midterms, gaining leverage over spending and oversight, though President Donald Trump retains substantial foreign policy power. Experts say Trump will likely maintain economic pressure on Iran, with potential military action possible before Democrats take seats in January. Tariffs may persist despite voter discontent, though Canada could see bipartisan support for renegotiation. Democrats plan to influence policy through committee hearings and the 2027 defense authorization, potentially reshaping aid to Israel and troop levels in Europe. Trump faces a narrowing window to cement his foreign policy legacy before 2028.
