BBC on Gaza

Don't really know what to think about BBC's stance on the aid advertisement for Gaza? I understand their desire to be impartial but how can they continue to remain so in the face of Israel's heavy handed, over reaction to the rocket attacks from Hamas and in effect turn their backs on the people who have suffered so appalingly over the last month. There has clearly been provocation from Hamas over a lengthy period of time but what Israel is reported to have done over recent weeks includes many war crimes - which makes it impossible for a news agency to remain impartial.. If it is so important for theBBC to remain impartial why have they reported in such a biased fashion about President Mugabe's abuse of power in Zimbabwe? The same could be said of their reporting concerning the Taliban in Afghanistan or that of Islamic terrorist attacks on free Western countries, all of which is heavily weighted. Why the fear of appearing less than impartial?
