Two US citizens held hostage be Hamas have been released.
I guess a few in Hamas realize that when the IDF said destroying Hamas would be the primary focus of Israel's efforts, and that hostages and civies would be of secondary priority, it means those hostages are not going to stop the IDF from striking Gaza, and doing what it needs to in order to deal with the issues there.
Hamas is realizing that human shields only work if the enemy isn't willing to lose the hostages to kill the Hamas members.
