Words have meanings and if you were more familiar with the language you would understand the word, murder, has no place in any discussion in any conversation about the conflict.
The Palestinian children and other noncombatants who have suffered or died in this conflict are entirely the responsibility of the Palestinian leaders who were stupid enough and insane enough to have started this war, which never held any possibility of gain for the Palestinians, and then hide behind the civilian population, and then demanded the world save them. What has happened to the Gazans is a tragedy of their own making, just as the Nakba was.
