Hamas is wiped out and its infrastructure destroyed
This is what has started to worry me. If Destroy Hamas means destroy a terrorist organisation. If Destroy it's infrastructure means destroy the tunnels and gen points. Then that's all fine.
BUT is Hamas a distinct organisation with set members? Or has it got very fuzzy edges. I suspect the Israeli government means Hamas the organisation, those who voted for them in 2006, those who might have voted for them because they were alive them, all those who support them now, or might or might in the future... That is why marches in London are described as support of Hamas. I suspect Hamas is being used to equal Palastinian.
Hamas, being the Government of Gaza, owns all the infrastructure - including schools, hospitals and everything else the country needs to function. Destroy Hamas infrastructure I suspect is being used to mean destroy the country and everything in it.
Basically - the Israeli government wants to wipe out Gaza and all its people. That is what they mean by wiping out Hamas and destroying its infrastructure.
