King Abdullah has died. Whither Saudi Arabia?

As The New York Times put it: “The king’s death adds yet another element of uncertainty in a region already overwhelmed by crises and as Saudi Arabia is itself in a struggle with Iran for regional dominance.”

Some places to read about the transition:

“King Abdullah, Who Nudged Saudi Arabia Forward, Dies at 90”

“Saudi Arabia’s King Abdullah Dead”

“Abdullah of Saudi Arabia, a wily king who embraced limited reform, dies”

“King Abdullah of Saudi Arabia dies”

What do you think will be the trajectory of the Wahhabi sect of Sunni Islam in the 21st Century?
