Actually yes. For both shia and sunni the goal is to bring all governments under sharia law.
Also - sunni believe that if they can bring the world into complete chaos the Mahdi will return.
Does anyone doubt that when Iran gets nuclear bombs that they will use them as soon as possible? Who should we blame when that happens and millions of people are killed? Should we blame the Iranians who are completely predictable? Or should we blame Obama, Clinton, Kerry and all those who were complicit? Yes, Obama and Clinton and the Democrat Party when the world is plunged into chaos because of you, some of us will remember who made it possible.
