Apparently this latest attack by Hezbollah was the last straw for Israel.

Mahmoud Komati, deputy chief of Hezbollah's political arm, also told The Associated Press in an interview that his group will not lay down arms.
"The truth is — let me say this clearly — we didn't even expect (this) response.... that (Israel) would exploit this operation for this big war against us," said Komati.
He said Hezbollah had expected "the usual, limited response" from Israel to the July 12 cross-border raid, in which three Israelis were killed.
In the past, he said, Israeli responses to Hezbollah actions included sending commandos into Lebanon to seize Hezbollah officials or briefly targeting specific Hezbollah strongholds.
He said the Shiite group had anticipated there would be negotiations on exchanging the Israeli soldiers for three Lebanese prisoners in Israeli jails, with Germany acting as a mediator as it did before.
