As Hezbollah, Israel battle on border, Lebanon's army watches on sidelines

BEIRUT: Since Israel launched its ground invasion of Lebanon, Israeli forces and Hezbollah militants have clashed along the border while the Lebanese army has largely stood on the sidelines.

It's not the first time the national army has found itself watching war at home from the discomfiting position of bystander.

Lebanon's widely beloved army is one of the few institutions that bridge the country's sectarian and political divides. Several army commanders have become president, and the current commander, Gen. Joseph Aoun, is widely regarded as one of the front-runners to step in when the deadlocked parliament fills a two-year vacuum and names a president.

But with an aging arsenal and no air defenses, and battered by five years of economic crisis, the national army is ill-prepared to defend Lebanon against either aerial bombardment or a ground offensive by a well-equipped modern army like Israel's.

The army is militarily overshadowed by Hezbollah. The Lebanese army has about 80,000 troops, with around 5,000 of them deployed in the south. Hezbollah has more than 100,000 fighters, according to the militant group's late leader, Hassan Nasrallah. Its arsenal - built with support from Iran - is also more advanced.
