I doubt they would have waited 126 days if targeted approach was able to happen from the get go.
If Hamas continue to manipulate, hide and use civilians in spite of being instructed to hand back over the hostages what choice does Israel have?
Because if they do nothing then Netanyahu doesn't care?
And if they try and get them then they are causing causalities.
For whatever reason some people will be going along with hiding and preventing hostages from being released. It is them that put their own people under risk of being killed. No country would just stand back and do nothing. We still have no confirmation (verified) that kfir Bibas is dead? Or the rest of his family? Noa who was raped and pulled by her hair into Gaza? Hersch with his arm blown off.
Of course targeted response is better but if there is no where else than rafah holds the key to the hostages and they have a duty to return them.
