Obsolete makes the point that you can never have true objectivity. Actually, the DEC's video appeal does present a pretty balanced case. It says very clearly at the beginning 'it is not about the rights and wrongs of the conflict.' This is a humanitarian appeal and this allows me to give another opportunity for a donation to be made- a basic plea for help without any need to resort to post-modernist analysis!
Post script: James Forsyth has a post on this over at Coffee House. His argument leads to the inevitable conclusion that you can not have a humanitarian appeal in the event of there being controversy around a conflict. What are the DEC meant to do? Have images of rolling meadows and cute rabbits to a soundtrack of It's a beautiful world? I don't think the anti-Israeli accusation that he makes is at all warranted and is verging on the offensive.
