When considering the Islamic world, Turkey is the best example of a country where democracy irreversibly gained a foothold despite religious and cultural traditions still respected today.

There is a good chance Donald Trump won't survive four years. Conflict of interest is the biggest danger for Trump. He is destroying one of the pillars of the free world.

I am confident the damage done by ruling through family and friends will be made impossible by future regulation.
