"Is the Hamas mentality"
This has nothing to do with the subject of this thread - the attempts by the Israelis to all-but starve the Palestinians into submission with its blockade, which is aimed at the Palestinian people as a whole - described, rightly in my opinion, as an act of humanity aimed directly at non-combatants.
Whatever soldiers do to soldiers at the behest of politicians is a separate argument altogether; this is little short of using civilians as human shields.
