Operation Cast Lead alone resulted in over 300 children and almost 100 women being killed by Israeli airstrikes and artillery. It may be that IDF commanders do not begin an operation like this specifically deciding they want to kill children or civilians in general, but it's quite obvious that they do not care if they do. After Cast Lead, Israel was roundly condemned by the UN and international community (except the US, Canada, Australia, and a couple other shitholes) and accused of war crimes by the UN.
