There will be no second Nakba, so if that is their endgame I agree.
Israel’s endgame should be;
1. Permanent ceasefire
2. Hostage/Prisoner exchange
3. End to the seige
Hamas is going nowhere, they’ve been around 40 years.
The best Israel can do is implement policies that drive down their support among the Palestinians in Gaza and the West Bank.
In the long run, work towards two states.
