I doubt Saudi Arabia will ever be a liberal society but these are some of the first steps to equality in that country. I'm sure there will be a few more changes to come but that's probably it. For a country with such strict laws and rules? They'll bend some of them but with all of the princes that country seems to have, I don't think it will last nor will they ever be that liberal.
These new changes are great or the Saudi people but will they last till the next prince comes to power?
