This place has been the expected start of WWIII for the duration of the Cold War and a bloody mess of atrocities on all sides for longer than that.
But there really is a less world-destroying end to this. When the hostages are returned and sufficient Hamas leadership is dead and resources destroyed, Israel will pull out. US will pour in aid, with the help of neighbors like Egypt.
Then comes the hard part, but much less violent: diplomacy. How do we get some sort of working agreement between the parties such that Israel feels safe and Palestinians aren’t too repressed? Everyone thought we had this a few years ago but then Hamas took over with the promises of terrorisn and destruction.
