(FILES) Former US President and Republican presidential candidate Donald Trump (L) speaks alongside Andrei Kozlov (R), an Israeli hostage who was captured by Hamas on October 7, 2023 and freed by the Israel Defense Forces, at the Israeli-American Council (IAC) National Summit in Washington, DC, on September 19, 2024. Conflict in the Middle East has weighed heavily on the US presidential campaign over the last year, and now -- as tensions escalate further -- it could sway November's election. Democratic candidate Kamala Harris finds herself treading on eggshells as she upholds President Joe Biden's support for key ally Israel, while running the risk of alienating Muslim and Arab American voters. Meanwhile, Donald Trump has pounced on the conflict to warn of a third world war -- an apocalyptic prognosis that he blames on the incumbent administration.
