From Stephen Kinzer at politico.com:
It’s far too dangerous to take sides in the proxy war between the two great Sunni and Shia states. In fact, our interests are more aligned with Tehran’s.
Only two Muslim powers remain standing in the Middle East, and suddenly they are on the brink of war. Our old friend, Saudi Arabia, carried out one of its routine mass beheadings last week, and among the victims was a revered Shiite cleric. Our longtime enemy, Iran, which is the heartland of Shiite Islam, was outraged. Furious Iranians burned the Saudi Embassy in Tehran. The next day, Saudi Arabia broke diplomatic relations with Iran.
The United States should do everything possible to avoid choosing sides in an intensifying proxy war between the dominant Shiite and Sunni powers in the Middle East. Though history tells us we should tilt toward Saudi Arabia, our old ally, if we look toward the future, Iran is the more logical partner. The reasons are simple: Iran’s security interests are closer to ours than Saudi Arabia’s are.
Most trouble in the Middle East emerges from ungoverned spaces—the disputed lands of Iraq, Syria, Palestine, Libya and other countries where many people live beyond the reach of legitimate government. This crisis is different. It pits two stable states against each other.
But taking Saudi Arabia’s side would be a disaster. True, militarily the two appear pitifully mismatched. Saudi Arabia is among the world’s best armed states. It has spent vast sums to buy the world’s most advanced war-fighting systems, most of them from the United States. Iran, by contrast, has been under heavy sanctions for decades. Its army is not much better equipped than it was during the Iran-Iraq War 30 years ago.
The confrontation becomes equalized, however, when motivation is factored into the equation. Saudis are notorious for their aversion to sacrifice. They hire foreigners to do most of the kingdom’s daily labor. Few Saudi men would dream of risking their lives for their country. For its war in Yemen, Saudi Arabia has recruited hundreds of mercenaries from Colombia. The Saudis have enough air power to devastate almost any country on earth. Wars are won on the ground, though, and there Saudi Arabia is pitifully weak.
The Iranians are different. If they believe their faith is under threat, they will pour onto battlefields even if they have to fight with slingshots. That difference in patriotic fervor makes sense. Saudi Arabia has existed for 83 years, Iran for more than 2,500.
Saudi Arabia’s decision to provoke this crisis was aimed at least in part at forcing the United States to take sides. Supporting Saudi Arabia over Iran, however, would be a way of harming our own interests.
