I do not accept that civilians are targeted

I presume by that you mean that though the weapons have indeed aimed at targets who were civilians(including many many children) , you believe the claims of the people who fired them that they were intending to kill people who were not civilians.   I somehow doubt that you would accept similar claims by people directing weapons at Israelis...

A suggestion for a more constructive discussion. Jim writes a post fairly summarising the case for Israel as he understand it, and Keith writes a post fairly summarising the case for Palestine. "Fairly" being the operative word.
