There is killing and there is murder. Murdering innocent civilians is what Israel did. On purpose, over and over, and with glee, might I add.
Warning people to get the heck out, and having the enemy even YET put the innocents in the line of fire, is not murder. It is killing, yes.
If you don't understand the difference, then I guess you're too mentally dull to understand the nuances of murder in the first degree, second degree, and various degrees of manslaughter.
But that lack of understanding would be YOUR problem, not ours.
