In 6 months the IAF dropped double the tonnage of bombs on Gaza than were dropped on the industrial German city of Koln during the entirety of WW2. If that wasn't bad enough, the IDF engaged in the systematic demolition of vast swathes of buildings and infrastructure in a deliberate attempt to render the strip uninhabitable. The aim of course was to facilitate the ethnic cleansing of Gaza as well as the physical destruction of as many civilians as could be managed without too much western upset - which turned out to be quite a lot.
Hamas is free to surrender at any point. The Palestinians are free to reject Hamas, appoint new civilian leadership and sue for peace, they’ve chosen not to do so, they’ve chosen not to do so for decades. My sympathies have expired, they can make peace or die, their choice.
