(FILES) US Vice President Kamala Harris and Israeli Prime Minister Benjamin Netanyahu arrive for a meeting in the Vice President's ceremonial office at the Eisenhower Executive Office Building in Washington, DC, on July 25, 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.
