Its not speculation, you are just not fully aware of the dynamics and the process that involves unity? I believe there's a lot of wishful thinking on your behalf. And furthermore, you are dismissive of the geopolitics factors that will be faced in the uprising Shia and Sunni unity ?
Aren't you speculating more than needed?? Qatar and Kuwait are calling out against Israel and Saudi.
Turkey against US. Palestinians are ready for revolution. It'll all happen slowly but InshaAllah will.
Lets be optimistic and join hands. Rest leave things on Allah. He is the best of Planners. Period.
It would require a revolution in the Sunni world to overthrow the dictators oppressor that rule their countries, is this likely to happen? Unlikely. Are the Sunnis ready for revolution for the sake of unity with Shia's, and change the status quo of their political and social lives ??
