I suppose he is needed for negotiations and like @EllaDisenchanted I’m also not really sure who would initiate his arrest.
Yes! I hope they at least give the hostages families the peace of mind that comes with certainty. Then again there are many families in Gaza who don’t know what has happened to their children, so they might not have the heart to do that. I think if they want to continue trying to destroy each other, and inadvertently themselves, then they should carry on going lower and lower with their barbaric actions. If they want peace then they should take the difficult step of aiming to be better than those they perceive as their enemy. To me, the latter is a sign of strength, and the former a sign of weakness.
