It took quite some time, but eventually the Israel Defense Forces (IDF) changed its strategic assessment about Syria. We are talking about a dramatic change. Reminder: when the revolt in Syria broke out, all of Israel — be it the official, the secretive, the military or the diplomatic one — openly supported the rebels, eagerly awaiting the fall of Syrian President Bashar al-Assad. Then-Defense Minister Ehud Barak said in an interview, “Assad [the family] would fall in a matter of weeks.” On Israeli television channels, a news ticker constantly flickered at the bottom of the screen, reading: “Assad — the end!” A few months later, a question mark replaced the exclamation point in that ticker.

From an Israeli perspective, the fall of Assad’s regime would have led to the disbanding of the “axis of evil” that spans from Tehran to Beirut via Damascus. Most Israeli strategists would not sleep a wink because of it. If Syria were to fall, Iran would be isolated and Hezbollah neutralized. This would also affect the nuclear race and the balance of power vis-a-vis Israel. That was the thought in Israel back in the day.

The Syrian revolt is now three years old. Despite a rough infancy, it is maturing right before our eyes, with no intention of leaving anytime soon. Israel’s strategic assessment has changed from a “few weeks” to much longer. At this juncture, Israel Defense Forces top brass believe that the struggle in Syria could last as long as a decade. Wording this cautiously, a very high-ranking Israeli defense official told me: “We’re facing a decade of struggle in the Syrian environs.” Either way, Israel believes that the Syria we had come to know over the past few decades is gone. That Syria — where a balanced and complex coalition of minorities was able to maintain a stable, quiet and seemingly cohesive state — is a thing of the past. What will replace it? This is precisely what the battle, which could last for many years, is all about.

“It’s like flipping a coin,” a senior IDF official commented. “Either way, the result would be bad. A victory of a Russian-backed radical axis that consists of Iran-Syria-Hezbollah is not a positive thing for Israel. But on the other hand,” he added, “the concentration of all the global jihad madmen in Damascus and the Golan Heights is also a disconcerting development. So as far as we’re concerned, the alternatives are bad either way. And there’s also the possibility that these alternatives would coexist, which means that the current situation could last for many more years. Assad will keep his grip in Damascus and the Alawite strongholds, while jihadist forces will grow stronger and take control of all the other areas.”
