There is a generation gap in Hezbollah. Hezbollah began as a Shiite radical group inspired by the Iranian Islamic Revolution. In that context, Hezbollah represented a militant, nonsecular alternative to the Nasserite Fatah, Popular Front for the Liberation of Palestine, and other groups that took their bearing from Pan-Arabism rather than Islam. Hezbollah split the Shiite community in Lebanon -- which was against Sunnis and Christians -- but most of all, engaged the Israelis. It made a powerful claim that the Palestinian movement had no future while it remained fundamentally secular and while its religious alternatives derived from the conservative Arab monarchies. More than anyone, it was Hezbollah that introduced Islamist suicide bombings.

Hezbollah had a split personality, however; it was supported by two very different states. Iran was radically Islamist. Syria, much closer and a major power in Lebanon, was secular and socialist. They shared an anti-Zionist ideology, but beyond that, not much. Moreover, the Syrians viewed the Palestinian claim for a state with a jaundiced eye. Palestine was, from their point of view, part of the Ottoman Empire's Syrian province, divided by the British and French. Syria wanted to destroy Israel, but not necessarily to create a Palestinian state.

From Syria's point of view, the real issue was the future of Lebanon, which it wanted to reabsorb into Syria, or at the very least economically exploit. The Syrians intervened in Lebanon against the Palestine Liberation Organization and on the side of some Christian elements. Their goal was much less ideological than political and economic. They saw Hezbollah as a tool in their fight with Yasser Arafat and for domination of Syria.

Hezbollah strategically was aligned with Iran. Tactically, it had to align itself with Syria, since the Syrians dominated Lebanon. That meant that when Syria wanted tension with Israel, Hezbollah provided it, and when Syria wanted things to quiet down, Hezbollah cooled it. Meanwhile the leadership of Hezbollah, aligned with the Syrians, was in a position to prosper, particular after the Israeli withdrawal from Lebanon.

That withdrawal involved a basic, quiet agreement between Syria and Israel. Israel accepted Syrian domination of Lebanon. In return, Syria was expected to maintain a security regime that controlled Hezbollah.
. . .
Syria could now claim to have no influence or obligation concerning Hezbollah. Hezbollah's leadership lost the cover of being able to tell the young Turks that they would be more aggressive, but that the Syrians would not let them. As the Syrian withdrawal loosened up Lebanese politics, Hezbollah was neither restrained nor could it pretend to be restrained. Whatever the mixed feelings might have been, the mission was the mission, Syrian withdrawal opened the door and Hezbollah could not resist walking through it, and many members urgently wanted to walk through it.
. . .
In addition, it allowed Iran to reclaim its place as the leader of Islamic radical resurgence. Al Qaeda, a Sunni group, had supplanted Iran in the Islamic world. Indeed, Iran's collaboration with the West allowed Tehran to be pictured among the "hypocrites" Osama bin Laden condemned. Iran wants to become the dominant power in the Persian Gulf, and one part of that is to take away the mantle of Islamic radicalism from al Qaeda.
. . .
Hezbollah, by its nature and its relationships, really did not have much choice. It had to act or become irrelevant.
