Despite pressure from Donald Trump, a hostage deal between Hamas and Israel is not guaranteed. Trump's power over Hamas is limited, and his power over Israel is debatable. While there are pressure points on Hamas, Trump's presidency is also a pressure point for both Hamas and Israel. Negotiations have been ongoing, but there are still disagreements on key issues such as the end of the war and the release of hostages. Concrete and specific pressure from Trump may be necessary to push the sides to make concessions and reach a deal.
