At this point, is anyone completely sure whose children were in that building? It would take the lowest possible subhuman to put someone else's children to death for propaganda purposes, but the sub human who would put his own children to death for that reason would be off the charts. They could not even be classified as subhuman, they would be nonhuman.
It's by no means clear that Israeli forces actually did kill them. It seems that the Israeli attack that dropped bombs near this building occurred at about 2AM, and the explosion that brought the building down was about 7AM.
If it wasn't an Israeli bomb, what was it? Could it have been a Hizbollah controlled demolition?
I for one would not put it past them to do just that.
Moreover, if there was, as it seems a six hour period between the Israeli acctack and the collapse of the building, why were there still people inside? Were they kept there?
