The New Cold War

The Wall Street Journal--There has long been bad blood between Iran and Saudi Arabia, but popular protests across the Middle East now threaten to turn the rivalry into a tense and dangerous regional divide

For three months, the Arab world has been awash in protests and demonstrations. It's being called an Arab Spring, harking back to the Prague Spring of 1968.

But comparison to the short-lived flowering of protests 40 years ago in Czechoslovakia is turning out to be apt in another way. For all the attention the Mideast protests have received, their most notable impact on the region thus far hasn't been an upswell of democracy. It has been a dramatic spike in tensions between two geopolitical titans, Iran and Saudi Arabia.

This new Middle East cold war comes complete with its own spy-versus-spy intrigues, disinformation campaigns, shadowy proxy forces, supercharged state rhetoric—and very high stakes.

"The cold war is a reality," says one senior Saudi official. "Iran is looking to expand its influence. This instability over the last few months means that we don't have the luxury of sitting back and watching events unfold."

On March 14, the Saudis rolled tanks and troops across a causeway into the island kingdom of Bahrain. The ruling family there, long a close Saudi ally, appealed for assistance in dealing with increasingly large protests.
