Across the globe, people in city squares and living rooms, ballrooms and villages cheered the election of Barack Obama as U.S. president, raising hopes that America's first black commander in chief would herald a less confrontational America.

People crowded before TVs or listened to blaring radios for the latest updates. In Sydney, Australians filled a hotel ballroom. In Rio, Brazilians partied on the beach. In the town of Obama, in Japan, dancers cheered in delight when their namesake's victory was declared.

Many who live in countries where the idea of a minority being elected leader is unthinkable expressed amazement and satisfaction that the United States could overcome centuries of racial strife and elect an African-American -- and one with Hussein as a middle name -- as president.

"What an inspiration. He is the first truly global U.S. president the world has ever had," said Pracha Kanjananont, a 29-year-old Thai sitting at a Starbuck's in Bangkok. "He had an Asian childhood, African parentage and has a Middle Eastern name. He is a truly global president."

In an interconnected world where people in its farthest reaches could monitor the presidential race blow-by-blow, many observers echoed Obama's own campaign mantra as they struggled to put into words their sense that his election marked an important turning point.

"I really think this is going to change the world," gushed Akihiko Mukohama, 34, the lead singer of a band that traveled to Obama, Japan, to perform at a promotional event for the president-elect. He wore an "I Love Obama" T-shirt.

The magnitude and emotion of the world reaction illustrated the international character of the U.S. presidency. Many look to Washington as the place where the global issues of war and peace, prosperity or crisis, are decided.

"This is an enormous outcome for all of us," said John Wood, the former New Zealand ambassador to the U.S. "We have to hope and pray that President Obama can move forward in ways which are constructive and beneficial to all of us."

Hopes were also high among those critical of President Bush's policies that an Obama victory would bring in a more inclusive, internationally cooperative U.S. approach. Many cited the Iraq war as the type of blunder Obama was unlikely to repeat.

At a party in Rio de Janeiro where Brazilians and Americans watched results come in, 33-year-old music producer Zanna said an Obama win would show that "Americans have learned something from the bad experiences of the Bush administration and that they choose well -- that they choose Obama."

Indeed, even as they raised expectations, many U.S.-watchers were quick to point out that Obama would have to confront enormous problems once in office: wars in Iraq and Afghanistan, tenacious difficulties in the Middle East and North Korea, a world economy in turmoil.

Europe, where Obama is overwhelmingly popular, is one region that looked eagerly to an Obama administration for a revival in warm relations after the Bush government's chilly rift with the continent over the Iraq war.

"At a time when we have to confront immense challenges together, your election raises great hopes in France, in Europe and in the rest of the world," French President Nicolas Sarkozy said in a congratulations letter to Obama.

Some South Koreans said they hoped Obama -- who has said he favors direct engagement with North Korea -- would press North Korean leader Kim Jong Il on human rights issues and the alleged kidnappings of hundreds of South Koreans.

Skepticism, however, was high in the Muslim world. The Bush administration alienated those in the Middle East by mistreating prisoners at its detention center for terrorism suspects at Guantanamo Bay, Cuba, and inmates at Iraq's Abu Ghraib prison -- human rights violations also condemned worldwide.

Some Iraqis, who have suffered through five years of a war ignited by the United States and its allies, said they would believe positive change when they saw it.

"Obama's victory will do nothing for the Iraqi issue nor for the Palestinian issue," said Muneer Jamal, a Baghdad resident. "I think all the promises Obama made during the campaign will remain mere promises."

In Pakistan, a country vital to the U.S.-led war on the al-Qaida terrorist network and neighbor to Afghanistan, many hoped Obama would bring some respite from rising militant violence that many blame on Bush.

Still, Mohammed Arshad, a 28-year-old schoolteacher in the capital, Islamabad, doubted Obama's ability to change U.S. foreign policy dramatically.
