Do you really not equate a kill ratio of over 175/1 as a massacre? over 300 children were killed, and if you read the link to the
Guardian article you would see that "The offensive left 16 medics dead. Nearly all of them were killed by Israeli fire while trying to save lives, and many more were wounded. According to the World Health Organisation, more than half of Gaza's 27 hospitals were damaged by Israeli bombs. Two clinics were completely destroyed and 44 others received damage."
Well, Israel has prevented access to Gaza to most of the press and UN inspectors, so numbers will always be in doubt, but there is no doubt about the 300 children, mostly shot, and many in the head. Even counting only the children that's a kill ratio of about 38 : 1; 38 children to each trained soldier killed. So which part of the word 'massacre' is inappropriate?
