The easiest way to get the hostages back is the Russian method in Lebanon and Chechnya. Get a military court to convert Bargouttis’ sentence to the death penalty. Unless 40 hostages are not released. If they do not comply then execute him. Do the same down the line. If it does not work you have no prisoners to exchange and it would be bodies for hostages. and you could throw in all the Judea and Samaria prisoners and expel the to Gaza.
