What is standing in the way of a ceasefire between Israel and Hamas in the war in Gaza?

On Ian Explains, Ian Bremmer unpacks the challenges and obstacles to achieving a ceasefire agreement in the Israel-Hamas war. The stakes are, as ever, incredibly high, and the humanitarian crisis has only gotten worse since the war began. Since October 7, around 40,000 Palestinians have been killed in the conflict, according to the Gaza Health Ministry, and the UN estimates that 60% of Gazan homes and 80% of commercial buildings and schools have been destroyed or damaged. If the fighting doesn’t end soon, over a million Gazans will face near-total starvation by mid-summer.
