President Joe Biden said Thursday Israel’s military should be “more careful” to save Palestinian civilian lives. His comments came as U.S. national security adviser Jake Sullivan met Prime Minister Benjamin Netanyahu and his war cabinet in Tel Aviv. Israeli Defense Minister Yoav Gallant told Sullivan Israel’s campaign in Gaza would continue well into 2024.

Defense Minister Yoav Gallant: “It will take and require a long period of time. It will last more than several months. But we will win, and we will destroy them.”

According to the White House, Sullivan told Israeli leaders the U.S. expects Israel’s military to soon switch to “lower-intensity operations.” The White House did not give a timeline for the change, but The New York Times cited four unnamed U.S. officials who said Biden wants to grant Israel three weeks to switch to “more precise tactics.”
