As someone recently said "Never again is now."
That was said when Bibi thought Israeli society was unified behind the initial war aim. Which was destroy hamas savages and get hostages back in the process. But hamas knows Israel’s weakness is that they will endanger their whole existence for 1 hostage, let alone 200+. And you can see the war aims changing day by day and the softening up process of letting the Israeli public know that destroying hamas was more of an aspiration thing rather than a true goal. Bibi will continue his ‘heavy blow’ charade till he bows out or is forced out.
