"With The Saudi King Ailing, Succession Speculation Begins "

MELISSA BLOCK, HOST:

Saudi Arabia's King Abdullah tried to reassure his country today that it can handle the challenge of low oil prices. But his statement was read by the Saudi prince, next in line for the throne. The king, who is in his early 90s, is in a hospital being treated for pneumonia. And that is fueling concern about succession in the Saudi monarchy and what that means for the U.S. NPR's Michele Kelemen reports.

MICHELE KELEMEN, BYLINE: Saudi watcher Rachel Bronson isn't expecting much chaos when King Abdullah eventually leaves the throne. She says Saudis don't want to further upset the oil markets. What concerns her is too much stability in a country that needs to be agile.

RACHEL BRONSON: As it is, it's a very slow-moving state. So anything that slows down decision-making makes it harder for them to fight terrorism and increase liberalization, continued liberalization, which is necessary. All of those things just become very slow. And that's what I worry about.

KELEMEN: Bronson is with the Chicago Council on Global Affairs and author of the book "Thicker Than Oil: America's Uneasy Partnership With Saudi Arabia." She says if power shifts to the next-in-line 79-year-old Crown Prince Salman, we could enter a period of very slow decision-making, something similar to what happened under Saudi Arabia's previous ruler, King Fahd.

BRONSON: He suffered a stroke in the mid '90s, and he continued to rule until he died in 2005. And so everything kind of came to a halt and he didn't have the agility and flexibility that you need at difficult times.

KELEMEN: And these are difficult times for Saudi Arabia. Its regional rivalry with Iran is a perpetual concern, and the threat of the self-proclaimed Islamic State militants, or ISIS, also tops the agenda. While Crown Prince Salman read out the king's speech today, he's not in good health, according to Simon Henderson of the Washington Institute for Near East Policy.

SIMON HENDERSON: Prince Salman himself has had at least one stroke, and he's also been slowing down. This is pretty well accepted by everybody. How you actually describe that slowing down is a matter of debate. I've tended to think it's some form of dementia.

KELEMEN: The next in line for the throne is Deputy Crown Prince Muqrin, the youngest surviving son of Saudi Arabia's founder. Some Saudi watchers think it's possible that power could move to him quickly and smoothly. But Henderson is not so optimistic.

HENDERSON: There's every reason why the rivalries and tensions in the house of Saud could lead to some real sharp divisions. That sort of event is bad news for policy against Iran, policy on oil and policy against ISIS.

KELEMEN: Saudi Arabia didn't do much, he says, when ISIS was threatening Syria and the previous government in Iraq. But he says Saudi Arabia now sees ISIS as a direct threat to the kingdom, and the U.S. needs to encourage Riyadh to do much more to counter the group's ideology.

HENDERSON: Washington cannot afford to have a hiatus in leadership in Riyadh. And it cannot afford to have anything but a smooth succession.

KELEMEN: The U.S. tends to avoid talking about such issues, though, says Bronson of the Chicago Council on Global Affairs.

BRONSON: We will continue to engage very actively with the leadership, whether it's the counterterrorism, whether it's intelligence. We will continue to interact, but I think we will stay very quiet.

KELEMEN: Henderson says that the U.S. should be sending discrete messages to Riyadh to make clear that any argument over succession will be damaging to both Saudi and U.S. interests. Michele Kelemen, NPR News, Washington.
