Why doesn't Israel 'accept' Hamas' deal to get out the remaining hostages in phase 2 and then go back to war afterwards?

It seems like the 2nd phase may not go through, with around 25 hostages assumed to still be alive. Why doesn't Israel just 'accept' the terms of the 2nd phase, get out all of the living hostages, and then re-enter to dismantle Hamas without the leverage they have of hostages? Obviously if me as some random guy has thought of this, it's not like the government/IDF hasn't.

It seems like an easy way to get out all of the hostages (at least all that are living) while eliminating Hamas afterward

Curious what you all think
