JERUSALEM (AP) — Israel has opened a new front in its attempts to halt weapons smuggling to Hezbollah, striking one of the group's positions inside Lebanon for the first time since the sides fought a war eight years ago.
This week's airstrike, meant to prevent the Islamic militant group from obtaining sophisticated missiles, is part of a risky policy that could easily backfire by triggering retaliation. But at a time when the Syrian opposition says Hezbollah has been striking major blows for President Bashar Assad's government in neighboring Syria by ambushing al-Qaida-linked fighters there, it shows the strategic importance for Israel of trying to break the Syria-Hezbollah axis.
While Israeli experts agree that Israel would never want to help al-Qaida, in this case Israel and the al-Qaida-linked fighters have as a common goal opposing Hezbollah and its alliance with the Syrian government. This puts them at least indirectly on the same side.
For now, the odds of a direct conflagration between Israel and Hezbollah appear low. The group has sent hundreds of fighters to Syria and is preoccupied with saving Assad's embattled regime. Syrian state media reported that army troops killed 175 rebels, many of them al-Qaida-linked fighters, near Damascus on Wednesday, but the Britain-based Syrian Observatory for Human Rights, a prominent opposition group, said it was Hezbollah forces that carried out the dawn ambush.
Israel considers both Hezbollah and the al-Qaida-linked Nusra Front to be grave threats. With a lack of good choices, Israel has avoided taking sides in the Syrian war, and in the short term, is content watching the two sides beat each other up. But in the long run, officials have expressed concerns about the battlefield expertise that Hezbollah has gained. Officials also suspect that despite repeated Israeli airstrikes on suspected arms shipments, Hezbollah has managed to get its hands on many sophisticated weapons, including Russian-made anti-aircraft and anti-ship missiles, ensuring that any future conflict with Israel will be far more intense than previous rounds of fighting.
"The type of scenario we have to plan for is extremely robust," said an Israeli military official, speaking on condition of anonymity because he was discussing an intelligence assessment. "It means the Israeli operational response has to be forceful, swift and decisive."
Israel and Hezbollah, an Iranian-backed Shiite group committed to Israel's destruction, battled to a stalemate during a monthlong war in the summer of 2006. Both sides have avoided any direct confrontation since a U.N.-brokered cease-fire ended the fighting, but each has been gearing up for renewed clashes.
Hezbollah rained some 4,000 rockets and missiles on Israel in 2006, mostly short-range, unguided projectiles. Israel believes the group now possesses 100,000 rockets and missiles. These include weapons with longer ranges, guidance systems and larger warheads, are capable of striking anywhere in Israel. The weapons come from Syria and Iran.
"Iran is handing out torches to the pyromaniacs," Israel's military chief, Lt. Gen. Benny Gantz, said during a tour of the northern front this week. "I suggest that everyone keeps in mind that underneath this quiet, a storm is brewing."
Israel believes Hezbollah has used the fighting in Syria as cover to transfer weapons back to Lebanon. Israeli leaders have repeatedly vowed to prevent Hezbollah from obtaining "game changing" weapons that could alter the current balance of power, and over the past year Israel has carried out a series of covert airstrikes in Syria that targeted shipments of weapons believed to be bound for Hezbollah. These included Russian-made anti-aircraft and surface-to-sea missiles, as well as advanced Iranian guided missiles.
Neither Israel nor Syria nor Hezbollah had confirmed any of the airstrikes, since going public might only escalate tensions. This changed after Monday's attack, the first inside Lebanon itself.
The attack took place on a known smuggling route along the Syrian-Lebanon border, and a senior Lebanese security official said it targeted long-range surface-to-surface missiles from Syria heading to a Hezbollah depot in Lebanon's Bekaa region. He said one Hezbollah official overseeing the operation was killed. The official spoke on condition of anonymity in line with regulations.
After two days of silence, Hezbollah confirmed the airstrike, saying it had caused material damage but no casualties. "We will retaliate for this Israeli aggression, and the resistance will choose the appropriate time and place as well as appropriate means to respond," Hezbollah said. The Israeli military declined comment, though senior security officials, speaking on condition of anonymity because of the secrecy of the mission, confirmed Israel's involvement.
Hezbollah's participation in the Syrian war is highly controversial and divisive in Lebanon and has eaten away at the group's wider base. But Hezbollah remains a formidable force in Lebanon, and has two ministers in the current national unity government that was recently formed following 11 months of impasse. After Wednesday's threats against Israel, the group may lose credibility if it does not retaliate.
"They are in a fix," said Hilal Khashan, a professor of political science at the American University of Beirut. "They very well understand that if they responded, the Israeli response will be overwhelming. They wouldn't be able to cope with the consequences of an all-out offensive at this time," he said. "That's why I tend to think they will swallow their pride."
A senior Israeli official said Hezbollah does not seem "eager to ignite" the area, but that Israel was following its moves "very carefully." He said one likely scenario could be a Hezbollah attack on Israeli targets abroad. The group has been blamed for a string of bombings on Israeli tourists and diplomats in Asia and Europe, including a July 2012 attack in a Bulgarian resort that killed five Israeli tourists and a Bulgarian bus driver. He spoke on condition of anonymity because he was not authorized to talk to the media about the matter.
Israeli military officials said late Wednesday that the army had raised its alert level along the northern front with Lebanon. Israeli TV stations also said the military had moved a battery of its "Iron Dome" rocket-defense system to the area.
The likelihood of retaliation is just one of the shortcomings of the Israeli airstrike policy. It also appears that the strikes have failed to halt the flow of arms to Hezbollah. In recent days, Israeli military officials have acknowledged that Hezbollah has likely succeeded in sneaking sophisticated weapons into Lebanon.
On Tuesday, Brig. Gen. Eli Sharvit, a senior naval official, told reporters the military operates under the assumption that Hezbollah now possesses Russian-made "Yakhont" anti-ship missiles, guided weapons capable of striking targets up to 300 kilometers (200 miles) out at sea. This could put Israeli warships, as well as natural gas installations, at risk. Officials say it is possible that Hezbollah has obtained other sophisticated weapons as well.
"We assume that what Syria possesses, Hezbollah has," he said.
Yiftah Shapir, a former Israeli air force officer who is now a military analyst at the INSS think tank in Tel Aviv, said the fact that sophisticated weapons have made their way to Hezbollah does not mean the airstrike policy has failed. "You can't expect every strike to have 100 percent success," he said.
Yet he said Hezbollah has transformed itself from a ragtag guerrilla group into a formidable fighting force. "These weapons though make it clear that since 2006 Hezbollah is no longer a terrorist organization, but an army and a well-equipped army," Shapir said.
