Also, the only cluster munition (display models) I've ever seen were painted bright colours, as they were intended to be a dissuasion to go somewhere rather than an unpredictable danger once you had.
Which is why kids tend to want to pick them up in the first place.
I see the argument about fighting on equal terms with Taliban etc, but I cannot support the use of cluster munitions in a foreign country not directly attacking my own. Would you send your kids to play in an area where cluster munitions are present? People in Kosovo, Afhanistan and Iraq have no choice.
