Crying victimhood and ceasefire when you start a war with an orgy of ecstatically livestreamed by GoPro murder, torture, rape, genital mutilation, beheadings and burnings is not credible. But it's the usual Arab cycle of, "we tried to kill you, we failed, we're the victims" since 1948.
"exterminate Hamas": In 1982 Israel got Arafat and the PLO out of Lebanon and deported to Tunisia. Sinwar is playing for time for the same outcome.
The war will continue until Israel regains pre-war deterrence restoration. Read the Hama Rules chapter of Thomas Friedman's From Beirut to Jerusalem. Hafez Assad's treatment of the Muslim Brotherhood revolt in Hama in 1982 tells you what to know about the Arab perception of power. Westerners simply do not understand that, in the Middle East, if your counterparty is not afraid of you, you should be very afraid.
As Dan Schueftan says, some problems have no solution, only mitigation. This will be true until the Arabs in the West Bank and Gaza abandon their delusional war of return and say, I'm not a refugee, I'm home in Gaza and Ramallah, I'm ready to live permanently in a Palestinian state side by side with the Jewish state of Israel.
