You can see video evidence of the IDF's use of White Phosphorus (WP) at the following link:
White phosphorus in Gaza: The victims
The video contains extremely disturbing images of medical damage, so I have not made the link live, you can copy and paste it into your browser if you are comfortable with R-rated medical images.
The other article I quoted in my last post on this, said, "The report repeats charges -- denied by Israel --- that white phosphorus was fired indiscriminately into Gaza streets." So then how did this Palestinian kid and half his family get WP burns, most of them to death? The poor kid in this video saw his sister and grandfather shredded bodily by the rockets. How terrible it is to have to say that it is unfortunate that his sister did not die immediately.
The use of violence is only justifiable in defense against the initiation of force by someone else, and only to the extent required to stop the aggression and/or administer conscionable punishment. I am of the opinion that the use of any bombs or indiscriminate explosive devices is almost never morally justifiable and that any use of such indiscriminate weapons must always come with criminal liability in the event of collateral damage, all the way up the chain of command. White phosphorus, in particular, is one of the most disgusting and barbaric weapons ever deployed.
