He has stopped talking about the restoration of the Global Caliphate. There is no more mention of the return of Andalusia. There is no more anticipation that Islam will sweep the world. He is no longer boasting that Americans run at the slightest wounds; that they are more cowardly than the Russians. He is not talking about future operations to swathe the world in fire but dwelling on past glories. He is basically saying if you leave us alone we will leave you alone. Though it is couched in his customary orbicular phraseology he is basically asking for time out.
As Vodkapundit would say: Required Reading
UPDATE: For insight on the "time out" see Hudna and Roger L. Simon
