When will the hostages return?
Edge cases
If a deal is struck before resolution date but they aren't returned yet, resolves NO
If freed by non-Israeli forces, resolves YES
If it's unclear what is the actual number of live hostages captured in the conflict, will resolve N/A
50% is calculated from the number of hostages taken alive, as reported by Hamas or estimaded by Israel. If a hostage was confirmed to be captured alive, but dies during captivity, it doesn't change the number of hostages taken alive, only that of those that can be returned alive.
