“I was positive that Trump will not make it to a second term. He was too hostile almost towards everybody. He is (more) fit to be a mafia leader than a president of the United States," said Adel Salman, 40, a high school English teacher in Baghdad.

"Let’s wait and see with the Biden presidency. And I’m saying to all Iraqis don’t count your chickens before they hatch. Is Biden better for Iraq? Let’s wait and see his acts."

Biden may face some of his most complex foreign policy challenges in the region: from wars in Libya and Yemen to reassuring the United States' Gulf Arab allies that Washington can protect them from enemy Iran, even though he has said he would return to the international nuclear deal with Tehran.

"Trump was our friend, he loved Saudi Arabia and protected it from enemies. He handcuffed Iran. Biden will let Iran free again and this will hurt us and the whole region," said Mohamed Al Anaizy, a Saudi Uber driver.

While Trump had cozy relationships with what critics say are increasingly authoritarian leaders in countries such as Saudi Arabia, Egypt and Turkey, Biden has promised to take a tough line on human rights.

Some critics of Egypt's President Abdel Fattah al-Sisi expressed hope that US policy would change, reposting a tweet by Biden from July in which he criticized Cairo's crackdown on political activists, and pledged: “No more blank checks for Trump’s ‘favorite dictator.’”

Sisi's government has denied accusations by human rights groups of widespread abuses.

Talk show hosts on Egypt’s tightly controlled TV channels have tried to play down the impact of a Biden victory, arguing that Egypt will adjust and adapt.

Sisi was quick to congratulate Biden. The leaders of Iraq, United Arab Emirates and Jordan also congratulated Biden.

Lebanese President Michel Aoun congratulated Biden and voiced hope for a "return to balance in American-Lebanese relations" during his term.

Nabil Boumonsef, deputy editor-in-chief of An-Nahar newspaper, told Reuters that the timing of the announcement of US sanctions on Friday on Aoun’s son-in-law Gebran Bassil, a prominent Christian politician, sent a message that Washington would continue to go after Lebanese politicians over accusations of corruption and aiding Hezbollah.

“Biden is more flexible and rational, but I do not expect fundamental changes, though there may be an easing of pressure with respect to sanctions until Biden’s Middle East team is in place," he said.

Ibrahim Matraz, a Yemeni journalist, was also pessimistic about prospects for a shift in US policy after years of conflict that have ravaged his country.

"We shouldn’t forget that Biden was vice president in Obama’s administration when the war began."

Trump's allegations of fraud in the election without providing evidence prompted some Arabs to say Washington had no right to preach about democracy in their countries, where leaders often win 99 percent of the vote in rigged elections.

"These elections show the real face of America, a country where elections are a farce with the loser not conceding defeat and claiming he won," said Adel al Natour, an industrialist in war-torn Syria, whose leaders face stringent US sanctions.
