Yes hostages have always been secondary from the start. I think the general feeling is that if they don't defeat Hamas then more people are at risk of being taken long term. As in it will seem to terrorists that is a tactic that works
When Iran took 70 American hostages. It took 440 days to get them released and half were killed before release. Then we have what happened to the Munich Olympic Israeli hostages that Arafat I think it was had killed. They were negotiating but the people got killed anyway.
In general the governments don't like negotiating with terrorists for hostage release. It tends to not work very well and just be a game. Also it makes the possibility of more hostages being taken at a later date increase
However let us see what Israel says/does next.
