In the days following the Hamas-led attack of October 7, 2023, President Joe Biden made clear his steadfast support for Israel. But as Israel’s military campaign continued and the humanitarian catastrophe in Gaza deepened, concern and opposition grew within his own administration over Israel’s conduct of the war and America’s continuing support.My guest, journalist Akbar Shahid Ahmed, interviewed more than 150 people for his important new book, Crossing the Red Line: Biden, His Advisors, and Israel’s War in Gaza. During our conversation, Akbar described how Biden relied on a small coterie of advisers, including Secretary of State Antony Blinken, National Security Adviser Jake Sullivan, and Brett McGurk, the National Security Council’s Middle East coordinator, leaving much of the State Department largely on the sidelines.
