Its a vey vast topic and I would like to skip this. When it comes to the time frame, I personally believe that there is nothing like that. One or two nations is highly unstable. With that we can't say the entire gulf. I know some of these nations very well and on the basis of that and some information gathered from some NRI , I can't believe this statement. Everyone has there on views and expression. But some times it's better not to express openly in public. This is completely my view. I am extremely sorry if I was wrong. Lets together pray and work hard for a better and smarter world .
