The decline of the LNM in the late 1970s, culminating in its collapse in the aftermath of the Israeli invasion of June 1982, sounded the death toll for many of the minor Lebanese leftist organizations. As the war progressed, many of these small factions – at least the more politically oriented ones – were destroyed in the violent power struggles of the 1980s. For the most part forced to go underground, some evolved to Islamic fundamentalist groups, whilst the less politicized simply degenerated into criminal street-gangs that engaged in assassinations, theft, smuggling, and extortion. As a result, only a small fraction of the truly ideologically committed groupings managed to survive the war to re-emerge in the 1990s as politically active organizations.
