Hamas has not negotiated. Instead they’ve made demands. Hamas started this knowing exactly what the repercussions would be . They made a calculated decision to sacrifice their own people to gain world sympathy. They also continue to cause Gazan’s deaths by making demands they’re not in a position to make and knowing they will never be met. The entire idea behind their thought process is that the international community will turn on Israel and they can get a Palestinian state out of this. Then their reign of terror will resume as the next phase would be to eradicate Israel.
