I pretty much agree with what you have written here. I think he assumes and expects a great deal when talking about the effect on the outside Arab world. However, as a way of cleaning house, and making conditions WITHIN Israel more settled, it is a very good start. Learning Arabic will definitely go a long way towards at least having a better understanding of the local Arab population and while I don't think it is necessary to adopt Arab culture, Israel is in the prime position to form a bridge between the West and the Arab world by accepting the Arab culture within its midst. Israel already is a Middle Eastern country, it's just that a lot of its inhabitants don't realize it.
