I would sack people like Mark Regev and get Ran Gido (UK attache) to publicly speak for you simply for damage limitation purposes. Regev simply reminds me of Tariq Aziz whereas Ran Gidor said exactly same thing as Regev but in a more sensible (and acceptable) manner. I don't think Israel was right in this manner but i think it's worth sacking the 'old boys' to make way for more sensible opinion.
