I understand what the writer is writing, but the matter is far more complex than the writer lets on. There is the issue of security where terrorist have used marriage to infiltrate Israel, and then there is the war of demographics that the Arab wages against Israel. The marriages previously were politically designed to flood Israel with Arabs hostile to the Jewish state. No one is stopping these families from living together in Judea and Samaria or Jordan (most have Jordanian citizenship). The author does not mention this.
