The dispute over Iran's nuclear program has again rocked oil markets. And Iran is threatening to close the Strait of Hormuz, which is just 34 miles wide yet serves as the passageway for 20 percent of the world's oil.

This is not a new drama. In fact, it was a recurring issue in the 1980s. Still, there's been relatively little activity among Gulf oil producers to find alternative routes to get their oil to market.

In the wake of the Arab Spring, some Muslims in North Africa are looking across the Mediterranean to Turkey as a potential model of a state that can be modern, Islamic and democratic.

But some analysts in the region say that model is flawed, and they are questioning Turkey's human-rights record and its dealings with the press.

An explosion in Tehran Wednesday killed an Iranian nuclear scientist while he was driving his car. It's the fifth such death in five years, and Iranian officials immediately blamed Israel. The attack is the latest manifestation of escalating tensions between Iran and the West.

In the Arab states that have ousted dictators and begun building new political and economic systems, many are looking to Turkey as an example of a modern, moderate Muslim state that works. Perhaps no country has seen its image in the Arab world soar as quickly as Turkey, a secular state that's run by a party with roots in political Islam. As part of our series on the Arab Spring and where it stands today, NPR's Peter Kenyon examines whether the "Turkish model" can be exported.

The year began on a note of cautious optimism on the Iran nuclear front. But talks in Geneva and Istanbul proved inconclusive, and the Arab Spring uprisings soon pushed Iran off center stage. And as 2012 approaches, observers see little reason for optimism regarding a diplomatic solution to the Iran nuclear dispute.

Iranian President Mahmoud Ahmadinejad, under attack from other conservative factions at home, continues to find a safe rhetorical haven in defending Iran's nuclear program — and in attacking the U.N. nuclear watchdog, the International Atomic Energy Agency.
