Tensions between the U.S. and Israel have escalated as Israel prepares for a potential ground incursion into Lebanon to combat Hezbollah, despite U.S. calls for caution and diplomacy. Israel has significantly weakened Hezbollah's leadership, including the assassination of its chief, Hassan Nasrallah, and other senior figures. While the Biden administration supports Israel's right to defend itself, it warns that further escalation could lead to an all-out regional war. President Biden has reiterated the need for diplomatic solutions to de-escalate the conflict and avoid a broader war in the Middle East. The situation remains fluid, with Israel planning limited incursions into Lebanon, complicating U.S. efforts to mediate a cease-fire.
