The Israeli military confirmed Wednesday it carried out the 2007 airstrike in Syria that destroyed what was believed to be a nuclear reactor, lifting the veil of secrecy over one of its most daring and mysterious operations in recent memory.
Although Israel was widely believed to have been behind the September 6, 2007, airstrike, it has never before commented publicly on it.
In a lengthy release, the military revealed that eight F-15 fighter jets carried out the top-secret airstrikes against the facility in the Deir el-Zour region, 450 kilometers (about 300 miles) northwest of Damascus, destroying a site that had been in development for years and was scheduled to go into operation at the end of that year.
Israel’s involvement has been one of its most closely held secrets, and it was not immediately clear why Israel decided to go public now. The military would not comment on its reasoning, but the move could be related to the upcoming memoir of former Prime Minister Ehud Olmert, who ordered the strike and has hinted about it for years, or it could be meant as a warning to archenemy Iran, which is active in Syria.
Israel and Syria have always been bitter enemies. Throughout Syria’s seven-year civil war, Israel has carried out well over 100 airstrikes, most believed to have been aimed at suspected weapons shipments destined for the Iranian-backed Hezbollah militant group. Both Iran and Hezbollah are allied with Syrian President Bashar Assad.
At the time of the 2007 strike, Syria accused Israel of invading its airspace, but gave no further details about the target.
The pre-mission briefing, made public Wednesday, stated that the operation should not be attributed to Israel so as to minimize the potential for an all-out war. It was ordered to be kept secret until further notice.
The strike was reminiscent of an Israeli attack against a reactor that was under construction in Iraq in 1981. The strike was later credited with preventing Saddam Hussein from acquiring weapons of mass destruction that could have been used in the Gulf War a decade later.
“The message from the 2007 attack on the reactor is that Israel will not tolerate construction that can pose an existential threat,” military chief Lt. Gen. Gadi Eisenkot said in Wednesday’s statement. “This was the message in 1981, this is the message in 2007 and this is the future message to our enemies.”
Eisenkot, who at the time commanded Israel’s northern front along the Lebanese and Syrian borders, said it marked Israel’s most comprehensive attack in Syria since the 1973 Mideast war, and that everyone involved knew it could spark a new one. He said only a handful of top commanders were aware of the plans for Operation “Outside The Box.”
The military said the F-15s took off from two bases in southern Israel at 10:30 p.m. on Sept. 5 and returned four hours later. Wednesday’s announcement also indicated the Syrian reactor was much closer to completion than previously reported.
From Israel’s perspective, the strike was an astounding success since it not only destroyed the site, but prevented further escalation and strengthened its deterrence in the region.
Air force commander Maj. Gen. Amikam Norkin said the current turmoil in Syria has further vindicated the strike, particularly since the reactor was in an area later captured by Islamic State militants.
“Imagine what situation we would be in today if there was a nuclear reactor in Syria,” Norkin said. “In historic hindsight, I think Israel’s decision to destroy the reactor is one of the most important decisions taken here in the last 70 years.”
Uzi Rabi, an expert on Iran at Tel Aviv University, said Israel’s surprising confirmation might be meant as a “warning sign” to Iran as it builds up its military presence in Syria. Israel has warned against the establishment of a permanent Iranian military presence in Syria, particularly areas close to Israel.
Last month, Israel shot down an Iranian drone that entered its airspace, triggering a clash in which an Israeli warplane crashed after being struck by Syrian anti-aircraft fire. Israel responded by bombing Syrian anti-aircraft batteries.
The military said it began obtaining information regarding foreign experts helping Syria develop the Deir el-Zour site in late 2004. Later it discovered that North Korea was helping Syria build a reactor to manufacture plutonium.
In his memoir, “Decision Points,” former President George W. Bush said the target was believed to be a Syrian nuclear reactor being built with North Korean assistance. He said Israel first asked the U.S. to bomb the site and then carried out an attack itself when Washington declined.
The strike came about a year after Israel’s inconclusive war against Hezbollah, in which Lebanese guerrillas battled Israel’s powerful army to a stalemate. The poor performance raised questions about Israel’s deterrent capabilities.
“Prime Minister Olmert’s execution of the strike made up for the confidence I had lost in the Israelis during the Lebanon war,” Bush wrote, adding that the Israeli leader rejected a suggestion to go public with the operation.
“Olmert told me he wanted total secrecy. He wanted to avoid anything that might back Syria into a corner and force Assad to retaliate. This was his operation, and I felt an obligation to respect his wishes,” Bush wrote.
Olmert has skirted around the issue, and military censors, for years, repeatedly saying that according to foreign sources Israel had been involved. After Bush’s account was published in 2010, Olmert said: “I don’t want (to), and I can’t deny it.”
Olmert, who was prime minister from 2006 until 2009 and was recently released from prison after serving time for corruption, is expected to delve more deeply into the issue in his upcoming book.
