Over the past few weeks, things have heated up again in Lebanon, with the U.S.-backed government on one side and the Syrian-backed Hezbollah on the other.

To many U.S. observers, this might be just another case of tensions flaring up in the Middle East. Do not be fooled. This is all about telecommunications policy--and the design of secure, attack-resistant data networks.

In an effort to stop Hezbollah's guerrilla fighters from communicating, Israel has in the past jammed the cell phone towers in the Hezbollah-controlled areas in southern Lebanon. Eager to make sure that didn't happen again, Hezbollah has covertly built out a fiber-optic network throughout the areas it controls.

(Hezbollah's leader, Hassan Nasrallah) said the government's decision to shut down Hezbollah's fiber-optic communications network was tantamount to a declaration of war. For the (central) government, the network represented an intolerable example of Hezbollah's efforts to set up an Iranian- and Syrian-backed state within Lebanon. Hezbollah justifies the network, which carried its communications during a 2006 war with Israel, as a vital security asset.
