What isn't captured in these threads but should be obvious to anyone looking 150 miles south is that conventional warfare, as conducted by every military power in the world, kills children and noncombatants in vastly higher numbers.
Use this attack to disqualify Israel's reckless and militarily pointless continued campaign in Gaza. Clearly, they had the capability not to conduct warfare the way they are there. Or, if you like, to condemn all warfare worldwide. But the attempt to single out the pager/radio attack as distinctively amoral is unpersuasive.
