DAMASCUS, Syria, July 27 - At the onset of the Lebanese crisis, Arab governments, starting with Saudi Arabia, slammed Hezbollah for recklessly provoking a war, providing what the United States and Israel took as a wink and a nod to continue the fight.
Now, with hundreds of Lebanese dead and Hezbollah holding out against the vaunted Israeli military for more than two weeks, the tide of public opinion across the Arab world is surging behind the organization, transforming the Shiite group's leader, Sheik Hassan Nasrallah, into a folk hero and forcing a change in official statements.
The Saudi royal family and King Abdullah II of Jordan, who were initially more worried about the rising power of Shiite Iran, Hezbollah's main sponsor, are scrambling to distance themselves from Washington.
An outpouring of newspaper columns, cartoons, blogs and public poetry readings have showered praise on Hezbollah while attacking the United States and Secretary of State Condoleezza Rice for trumpeting American plans for a “new Middle East” that they say has led only to violence and repression.
Even Al Qaeda, run by violent Sunni Muslim extremists normally hostile to all Shiites, has gotten into the act, with its deputy leader, Ayman al-Zawahri, releasing a taped message saying that through its fighting in Iraq, his organization was also trying to liberate Palestine.
Mouin Rabbani, a senior Middle East analyst in Amman, Jordan, with the International Crisis Group, said, “The Arab-Israeli conflict remains the most potent issue in this part of the world.”
Distinctive changes in tone are audible throughout the Sunni world. This week, President Hosni Mubarak of Egypt emphasized his attempts to arrange a cease-fire to protect all sects in Lebanon, while the Jordanian king announced that his country was dispatching medical teams “for the victims of Israeli aggression.” Both countries have peace treaties with Israel.
The Saudi royal court has issued a dire warning that its 2002 peace plan - offering Israel full recognition by all Arab states in exchange for returning to the borders that predated the 1967 Arab-Israeli war - could well perish.
“If the peace option is rejected due to the Israeli arrogance,” it said, “then only the war option remains, and no one knows the repercussions befalling the region, including wars and conflict that will spare no one, including those whose military power is now tempting them to play with fire.”
The Saudis were putting the West on notice that they would not exert pressure on anyone in the Arab world until Washington did something to halt the destruction of Lebanon, Saudi commentators said.
American officials say that while the Arab leaders need to take a harder line publicly for domestic political reasons, what matters more is what they tell the United States in private, which the Americans still see as a wink and a nod.
There are evident concerns among Arab governments that a victory for Hezbollah - and it has already achieved something of a victory by holding out this long - would further nourish the Islamist tide engulfing the region and challenge their authority. Hence their first priority is to cool simmering public opinion.
But perhaps not since President Gamal Abdel Nasser of Egypt made his emotional outpourings about Arab unity in the 1960's, before the Arab defeat in the 1967 war, has the public been so electrified by a confrontation with Israel, played out repeatedly on satellite television stations with horrific images from Lebanon of wounded children and distraught women fleeing their homes.
Egypt's opposition press has had a field day comparing Sheik Nasrallah to Nasser, while demonstrators waved pictures of both.
An editorial in the weekly Al Dustur by Ibrahim Issa, who faces a lengthy jail sentence for his previous criticism of President Mubarak, compared current Arab leaders to the medieval princes who let the Crusaders chip away at Muslim lands until they controlled them all.
After attending an intellectual rally in Cairo for Lebanon, the Egyptian poet Ahmed Fouad Negm wrote a column describing how he had watched a companion buy 20 posters of Sheik Nasrallah.
“People are praying for him as they walk in the street, because we were made to feel oppressed, weak and handicapped,” Mr. Negm said in an interview. “I asked the man who sweeps the street under my building what he thought, and he said: ‘Uncle Ahmed, he has awakened the dead man inside me! May God make him triumphant!' ”
In Lebanon, Rasha Salti, a freelance writer, summarized the sense that Sheik Nasrallah differed from other Arab leaders.
“Since the war broke out, Hassan Nasrallah has displayed a persona, and public behavior also, to the exact opposite of Arab heads of states,” she wrote in an e-mail message posted on many blogs.

In comparison, Secretary of State Condoleezza Rice's brief visit to the region sparked widespread criticism of her cold demeanor and her choice of words, particularly a statement that the bloodshed represented the birth pangs of a “new Middle East.” That catchphrase was much used by Shimon Peres, the veteran Israeli leader who was a principal negotiator of the 1993 Oslo Accords, which ultimately failed to lead to the Palestinian state they envisaged.
A cartoon by Emad Hajjaj in Jordan labeled “The New Middle East” showed an Israeli tank sitting on a broken apartment house in the shape of the Arab world.
Fawaz al-Trabalsi, a columnist in the Lebanese daily As Safir, suggested that the real new thing in the Middle East was the ability of one group to challenge Israeli militarily.
Perhaps nothing underscored Hezbollah's rising stock more than the sudden appearance of a tape from the Qaeda leadership attempting to grab some of the limelight.
Al Jazeera satellite television broadcast a tape from Mr. Zawahri (za-WAH-ri). Large panels behind him showed a picture of the exploding World Trade Center as well as portraits of two Egyptian Qaeda members, Muhammad Atef, a Qaeda commander who was killed by an American airstrike in Afghanistan, and Mohamed Atta, the lead hijacker on Sept. 11, 2001. He described the two as fighters for the Palestinians.
Mr. Zawahri tried to argue that the fight against American forces in Iraq paralleled what Hezbollah was doing, though he did not mention the organization by name.
“It is an advantage that Iraq is near Palestine,” he said. “Muslims should support its holy warriors until an Islamic emirate dedicated to jihad is established there, which could then transfer the jihad to the borders of Palestine.”
Mr. Zawahri also adopted some of the language of Hezbollah and Shiite Muslims in general. That was rather ironic, since previously in Iraq, Al Qaeda has labeled Shiites Muslim as infidels and claimed responsibility for some of the bloodier assaults on Shiite neighborhoods there.
But by taking on Israel, Hezbollah had instantly eclipsed Al Qaeda, analysts said. “Everyone will be asking, ‘Where is Al Qaeda now?' ” said Adel al-Toraifi, a Saudi columnist and expert on Sunni extremists.
Mr. Rabbani of the International Crisis Group said Hezbollah's ability to withstand the Israeli assault and to continue to lob missiles well into Israel exposed the weaknesses of Arab governments with far greater resources than Hezbollah.
“Public opinion says that if they are getting more on the battlefield than you are at the negotiating table, and you have so many more means at your disposal, then what the hell are you doing?” Mr. Rabbani said. “In comparison with the small embattled guerrilla movement, the Arab states seem to be standing idly by twiddling their thumbs.”
