22 July Washington Post - History Revisited in Lebanon Fighting by Edward Cody and Scott Wilson.

...Yet a look back over the past three decades suggests that the foe Israel is taking on today -- the Lebanese-based Hezbollah militia -- may be far harder to expel than the transplanted Palestinians it fought in southern Lebanon in the 1970s and '80s.

The history also suggests that Israel's previous military campaigns and occupations of Lebanon played a decisive role in creating this new enemy. Some analysts in Lebanon believe that the new bloodshed and a renewed attempt to fashion Lebanese society to Israel's advantage could generate yet another permutation, one that is perhaps even more irreconcilably hostile to the Jewish state.

"Now you risk producing something worse than Hezbollah, maybe al-Qaeda number two," said Fawaz Trabulsi, a Lebanese professor at the American University of Beirut who helped lead a leftist organization that fought Israeli troops alongside Palestinian guerrillas during the 1982 invasion.

"It's '82 all over again," Trabulsi said. "What's similar is the idea of destroying the infrastructure, of the PLO then, and now of Hezbollah. The difference is Hezbollah is Lebanese and you can't expel them."

The 1978 Operation Litani provided a clear lesson in the rules of unintended consequences. It was a swift success militarily; Israeli forces pushed across the border and moved about 20 miles north to the Litani River without serious opposition from primarily ragtag Palestinian defenders. They weren't native to the area or fully familiar with it -- they'd moved to it in the early 1970s to escape a crackdown in Jordan...

Its exploding young population, sons of those chased from southern homes, became the base of a new radical organization born several years later. Inspired by the 1979 Iranian revolution, it eventually took the name Hezbollah, or Party of God...

Yitzhak Bailey was teaching Middle East history at Tel Aviv University in 1982 when Israel's Defense Ministry called him with a job offer...

A native of Buffalo, N.Y., who arrived in Israel in the early 1950s, Bailey has made a specialty of Arab affairs, the culture of the nomadic Bedouin people in particular. But his task in the fall of 1982 was to evaluate the Shiite political landscape in south Lebanon and find Israel some friends there.

At the time, Israel had made common cause with Lebanon's Maronite Christians, who opposed the PLO's presence in Lebanon and feared for their place in a country with a growing Muslim majority. The Christian leadership was also willing to work openly with Israel.

Operating from an Israeli military base in Tyre, Bailey began traveling the region. He spent nights in family homes when he could, and tried to determine the most important political players in the Shiite south. Almost at once, he said, he began proposing in his reports a different approach to win allies in the crucial southern Lebanese region.

"All of Israel's eggs were in the Christian basket," Bailey said. "While the Shiites at the time were willing to be quite cooperative, they were not willing to say so openly." As members of a minority, many Shiites felt they needed protection from other factions in Lebanese society.

At the time, a Shiite Lebanese party called Amal was the most important party in the south. Once Israeli tanks and troops had dislodged PLO gunmen, Amal's influence increased dramatically. Amal was aligned in that period with more-liberal elements of the leadership of Shiite-dominated Iran, and the group tacitly accepted the Israeli role in the south. But once that cooperation became known, Bailey said, the movement broke apart.

Islamic Amal, as the radical splinter was called, began carrying out attacks on Israeli and Western targets. The group's popularity rose as Israel, responding to rising militancy, began tightening its hold with checkpoints, mass arrests and military operations that hit the civilian population hard.

The splinter group soon renamed itself Hezbollah.
