Israel was indiscriminately attacked by the ruling governmnent of Gaza, after Israel has abandoned Gaza. The allies in the Second World war, would have acted similarly or even worse that Israel. Hiroshima and Dresden are an example. Also a lot of civilian payed with their life in the Normandie landing. That is colateral damage. Gaza is a sad story that could have been avoided if the International community would be a harsher with a bunch of reactionary terrorists like Hammas.
