I strongly disagree with the idea that troops behaviour should not be scrutinised after an action, in the same way that Police or sports people's performance is required to stand up to examination for breaches of conduct. If there is no chance of scrutiny, then you end up with a riff-raff army, undisciplined and given a license to carry out any atrocities. During operation Cast Lead, the IDF was in a similar role to a teacher thumping- with a piece of pipe- a 10 year old and his mates for throwing stones. Over the top violence is nothing for any military unit to be proud of. Having served in the army myself, I would have been ashamed to have been a part of an operation like Cast Lead with such a horrendous toll in civilian casualties.
