After 15 months of collective grief and anxiety, three Israeli hostages left Hamas captivity and returned to Israel, and dozens of Palestinian prisoners walked free from Israeli jail, leaving both Israelis and Palestinians torn between celebration and trepidation as the ceasefire between Israel and Hamas took hold Sunday.

There is no detailed plan in place to govern Gaza after the war, much less rebuild it. Any return of Hamas will test the patience of Israel, which has said it will resume fighting unless the group is dismantled.
