A Little Arithmetic

According to The New York Times:

Hezbollah spent the last six years dispersing about 12,000 rockets across southern Lebanon in a vast web of hidden caches, all divided into local zones with independent command.

………

o attack Israel, Hezbollah dispersed its fighters with no distinguishing markings or uniforms or vehicles. Fighters access the weapons only at the moment of attack, and then disappear. This makes preventing the attack all but impossible. It is a significant modernization of classic guerrilla hit-and-run tactics. Israel has been unable to significantly degrade the numbers of rockets because of this approach. Hezbollah fired more than 100 a day at the start of this conflict; they are still firing more than 100 a day, despite Israeli bombardment.

12,000 rockets divided by 100 rockets per day gives 120 days. Hezbollah can't hold out longer unless Iran plays the North Vietnam role. (Even if it does, the Israelis can wait a little longer.)
