 I think this impossibility or this difficulty of imagining the future is itself an impact of trauma. The Nakba being kind of an ongoing trauma, it started but it never ended. When you don't mourn the past, it remains in your present and it blocks your vision of the future. I'm kind of reminded here with a quote from Edward Said, the future, like the past, is built by human beings. They, and not some distant mediator or savior, provide the agency for change.
