anniebach I don't think anyone is mocking the Saudi Arabian women who have campaigned hard to get this ban lifted - some of whom have been to prison for flouting the law.
What a lot of people feel, though, is that countries like ours should be more vocal in their criticism of the Saudi rulers' treatment of women, which really is nothing short of slavery (and should not be selling them arms).
And, as whitewave says, there is certainly a suspicion that this very small step in the right direction is being used to divert attention from what is happening (very quietly, because there is very little coverage in our media) in Yemen.
