Unless they want to kill the entire population of gaza then they won't be able to. One man's terrorist is another man's freedom fighter and just as every Catholic killed in N. Ireland recruited another 2 for the IRA, every Hamas fighter killed by Israel is used to recruit 2 more. There's never ending cycles here of "those bustards killed my dad/mum, brother/sister, mate, child etc etc" and while I understand the Israeli operation in Gaza it will not be successful and will and is losing Israel international support that it needs. And by understand the Israeli operation i mean eradicating Hamas is a legitimate aim but its also unachievable because Hamas is not a nice neat organisation and really is pretty indistinguishable from the civilian population of Gaza and so while I do not believe Israel set out to create genocide, mass genocide in Gaza is effectively the only way to eradicate Hamas.
