According to Ross:

"When Hezbollah was fighting Israeli "occupation," it was untouchable. But the general Arab narrative has been that the violence, meaning terrorism, is driven by occupation: no occupation, no violence. Hamas has already cast doubt on this narrative by launching attacks from Gaza after the Israeli withdrawal, but it is hard for Arab regimes to challenge Hamas's legitimacy. Hezbollah, however, is another story.

Ross goes on to list the many condemnations of Hezbollah's recent actions offered by the Arab countries of the region. He sees the situation as an opportunity--a tricky one, to be sure, filled with perilous traps and the need for delicate balance--to check Iran's rise in the region.

In recent years, Israel has pulled back from the Arab territories it formerly occupied and fortified its borders with the famous defensive fence. These acts had the effect of calling its enemies' bluffs. But this retreat was widely seen by those enemies as Israeli weakness rather than strength. Now Israel is trying to show that perception to be a false one."
