Is Israel responsible for the demography of Gaza? Should these children be considered an effective shield for Hamas, behind which they can launch attacks on civilians with impunity?
It seems to me the ones most responsible for putting children at risk are the parents who decided to have lots of them while penned in in a war zone run by belligerent terrorists, but I suspect you don't want to hear that. You seem pretty committed to blaming Israel for the miserable situation Gazans have created for themselves, the inevitable and predictable result of repeatedly choosing violence every time despite this conflict being unwinnable militarily.
