US parties split over Israel and Iran policy

Intense foreign‑policy debates about Israel and Iran are creating deep divisions within both the Democratic and Republican parties in the United States. In the Democratic primaries, two incumbent House members in New York were defeated by challengers who accused them of being too supportive of Israel, and two democratic‑socialist candidates with anti‑Israel platforms won nominations, prompting centrist leaders to warn of a party split. Matt Bennett of the centrist think‑tank Third Way said, “We’ve got to figure out a way so it doesn’t blow the party apart.”

On the Republican side, support for Israel and the war with Iran are fueling a split between isolationist voters who feel betrayed by President Trump’s intervention in Iran and hawkish members who criticize his negotiations as insufficient. Trump’s hold on the party remains strong, but internal dissent is evident as some Republican candidates lose primaries to pro‑Israel challengers. The rifts are influencing midterm election outcomes, shaping the battle for control of Congress, and could have lasting effects on the 2028 presidential race.
