Shortly after Israel assassinated the head of Hezbollah’s elite Radwan unit, Israeli Prime Minister Benjamin Netanyahu declared his country was working to “change the Middle East”. The same refrain came from Israeli politician Naftali Bennett, who tweeted on October 2: “Israel has now its greatest opportunity in 50 years to change the face of the Middle East…This opportunity must not be missed.”

As Lebanon’s Shiite community looks at the wreckage all around, it must find such examples of Israeli hubris deeply disturbing, and not a little infuriating. The region has a gift for thwarting the most ambitious plans of major regional and international actors. As Israel celebrates what it regards as the defeat of Hezbollah, those Lebanese who back the party surely have a different interpretation.

And they may well be correct. Hezbollah is more than a political-military party; it is an organisation anchored in one of Lebanon’s largest religious communities. This not only has earned it formidable loyalty, but also something more potent in the context of the Lebanese sectarian system: identification with the fate of the Shiite community, so that anything that harms the party would be seen by many in the community as weakening all Shiites.

This should be remembered as we look ahead at what could happen to Hezbollah once the conflict in Lebanon ends. However, it’s a certainty the party will have a mountain to climb when the carnage comes to an end. Hezbollah opened a front against Israel that virtually no one in Lebanon wanted, since everyone was conscious of how vulnerable the country was only four years after its colossal, and still unresolved, financial collapse.

With entire villages, towns and quarters in Beirut’s southern suburbs now in ruins, as Israel has transposed the brutality it deployed in Gaza to Lebanon, the one question on everyone’s mind is: Who will rebuild what was destroyed? This time, there is a general belief that there will be no outside money for reconstruction, including from Gulf countries, some of whom contributed a significant amount in 2006. Nor does it seem that Iran can spare funds to rebuild Shiite-dominated areas.

While this need not mean that its supporters will turn fully against Hezbollah, resolving this problem and reviving a traumatised community will easily be a decade-long task, one that will neutralise the party militarily for many years ahead —as the 2006 war did for just under two decades. In that context, two questions stand out.

The first is what happened to the vaunted “unity of the arenas” strategy that Iran and Hezbollah formulated just last year? The macabre conclusion is that the arenas have been unified in ruination, as Lebanon’s Shiite-majority districts go the way of Gaza. The Palestinian and Lebanese fronts in this strategy appear to have been nullified, as the Israelis are able to escalate to ever-higher levels of destruction without Iran and its allies being able to do the same.

The second is that if Hezbollah is unable to rearm and mobilise its devastated community to support a new war against Israel in the foreseeable future, of what value is the party to Iran? Should the Iranians then consider whether it is time to alter their strategy focused on extending their military influence throughout the Arab world, thereby avoiding a head-on collision with most Arab states, the US and even Israel?

At this point, the outlook of Iran’s leadership apparently has not changed, and it is improbable it will for as long as supreme leader Ayatollah Ali Khamenei is in power. But Iran’s two most potent regional allies in the fight against Israel — Hezbollah and Hamas — have undermined their respective publics’ ability to endure new wars, which has had a crippling effect on their, and Iranian, power.

What about Hezbollah’s margin of manoeuvre inside Lebanon? The party’s domestic hegemony has resulted in a gradual build-up of resentment in recent years, to the point where it is largely isolated in its fight against Israel today. No one is blaming the party openly, and animosity towards Israel is high, but few Lebanese endorse Hezbollah’s decision to open a southern front without bothering to consult its Lebanese partners, let alone the state.

This will have repercussions on Hezbollah’s ability to impose its priorities on the political class. It now seems improbable that the party will be able to bring in the president it favours, Suleiman Franjieh, against the wishes of Mr Franjieh’s Maronite Christian community. Many Christians regard Hezbollah’s insistence on Mr Franjieh as an example of arrogance, considering the party never allowed other communities to choose Shiite state officials.

With Hassan Nasrallah dead, and his probable successor and cousin Hashem Safieddine reportedly also dead, both killed by Israeli bombs, it’s unclear who has the authority and charisma to lead the religious Shiite community from now on.

Many eyes will now be turned to Nabih Berri, the 86-year-old Parliament Speaker, and most senior Shiite figure in the state. He sits at the centre of two logics dominating Lebanon today — a logic of Hezbollah-led resistance and a logic of the state, with many Lebanese believing no armed non-state actor should ever again be allowed to carry Lebanon unilaterally into a war. Mr Berri will play a major role in helping one of these logics to prevail. Which way will he lean? Lebanon’s fate may be determined by his choice. Didn't Naim Qassem, Hezbollah's interim secretary general, call the Speaker "our big brother" in a speech on October 8?
