Hizbullah, Iran's 'Crown Jewel' of Regional Influenceإقرأ هذا الخبر بالعربية
Lebanon's Hizbullah, blamed by Saad Hariri for his shock resignation as premier, has grown over the three decades since its founding into a mighty army used by Iran to project regional influence.
Hariri criticized the powerful Shiite movement for alleged meddling across the Middle East during a televised interview from Saudi Arabia on Sunday, his first media appearance since he stepped down on November 4.
Hizbullah has participated in Hariri's government for almost a year.
From Lebanon to Syria, Yemen, and Iraq, Hizbullah has matured into Iran's most useful "tool" -- drawing the ire of Tehran's regional rival Riyadh, analysts say.
Hariri's surprise resignation sparked worries that Lebanon would be caught in the crossfire of the bloody, decades-long power struggle between Saudi Arabia and Iran.
"This resignation indicates Saudi's will to put a stop to Iran's expansion," said international relations expert Karim Bitar.
Hizbullah had become Iran's "trump card" in the Middle East, added Bitar, of the Paris-based Institute of International and Strategic Affairs.
Since its founding in the 1980s during Lebanon's grinding war, Hizbullah has relied heavily on Iran for financial, political and military support.
It is the only faction to have retained its arsenal of weapons after the end of Lebanon's 15-year civil conflict in 1990.
Despite being branded a "terrorist" organization by the United States and Gulf countries and targeted with economic sanctions, Hizbullah has risen to play a decisive role in local and regional conflicts.
- 'Most important tool' -
"The most important Iranian tool in the region is Hizbullah," said Hilal Khashan, political science professor at the American University of Beirut.
Hizbullah has trained Iraq's powerful Hashed al-Shaabi paramilitary forces, Khashan said, and even has "operatives" in Yemen's war to back Shiite Huthi rebels targeted by Riyadh.
Closer to home, Hizbullah has fought ferociously in Syria to defend the government of President Bashar al-Assad, also an ally of Iran.
The group's intervention in Syria's six-year conflict was a major turning point that helped Assad's troops retake swathes of territory.
It also helped hone Hizbullah's own combat experience, transforming it from a guerrilla movement to a powerful fighting force with offensive capabilities.
Combining its military expertise and political savvy, Hizbullah has matured into Iran's "crown jewel" in the Middle East, said Joseph Bahout at the Carnegie Foundation think tank.
It now serves as a "model" for all Iran-allied groups in the region, from Syria's pro-regime militias to Iraq's Hashed al-Shaabi and the Iran-backed Huthi fighters, Bahout said.
These military ventures formed the crux of Hariri's criticism of Hizbullah during his landmark interview on Sunday from Riyadh.
Breaking his silence more than a week after his resignation, Hariri called on Hizbullah to commit to Lebanon's policy to "disassociate" from regional conflicts.
"I tell Hizbullah: it is in your interest, if we want to protect Lebanon... to leave some of the areas that you have entered," Hariri said.
He zoned in on Yemen, saying Hizbullah's involvement in the protracted conflict there had drawn Saudi's rage: "Did the kingdom have any position towards Hizbullah before the war in Yemen?"
- Conflict 'flare up' -
Hariri, 47, accused Iran and Hizbullah of taking over Lebanon and destabilizing the broader region when he stepped down on November 4.
That announcement sparked worries that Lebanon would be sent careening back into political and economic turmoil as Riyadh and Tehran vie for influence.
There were even fears of a new war with Israel, after Hizbullah chief Sayyed Hassan Nasrallah accused Saudi Arabia last week of asking the Israelis to bomb Lebanon.
Israel and Hizbullah have clashed several times, including in a month-long war in 2006 that killed 1,200 Lebanese -- mostly civilians -- and 160 Israelis, mostly soldiers.
But any new conflict between Lebanon and Israel risks spilling over into the broader region, experts have said.
"This time," said Bahout, "because of the extension in Syria and Iraq, it won't be a war on Hizbullah only. It will very quickly flare up."
Nasrallah's forces could respond to Israeli pressure by striking elsewhere.
For Bitar, a convergence of factors, including "an impulsive Saudi Arabia, backed by an equally, extremely impulsive American president, and rising rhetoric in Israel," could indicate a war was near.
"But at this stage, we are still in a system where there is mutual deterrence, a balance of terror," he said.
"The two parties know that an eventual war would be devastating for both sides."
