What Hamas did requires a response from Israel, and no amount of “truce now, k?” will be work. It’s sad, but the only course for Israel is to hit back, and hard. Anything less would be bending over and showing Hamas can do this again.
In other words, you can’t stab a person, and then go “whoa stahp” when the bleeding guy pulls a bigger gun on you.
Bystanderd will be hurt, but I hope it will be over quick and afterwards there can be a path towards something better.
