TEHRAN, Iran (CNN) -- He's been labeled by many as the "reformist," a man who can take Iran beyond the truculent anti-Western rhetoric of President Mahmoud Ahmadinejad. 

Moussavi was not seen as a reformer during his stint as prime minister during the 1980s. 

So, when Iran's government announced over the weekend that Mir Hossein Moussavi had lost in his bid to become the country's next president, young Iranians took to the streets by the thousands alleging ballot fraud. 

Thousands of others around the globe championed the cause on social-networking Web sites and agreed to wear green on Monday in solidarity with Moussavi's supporters. 

But what is often lost in the outrage is whether Iran would look different under a Moussavi presidency. Watch more about the vote » 

Though the 67-year old is credited for successfully navigating the Iranian economy as prime minister during a bloody eight-year war with Iraq in the 1980s, he also was a hard-liner whom the Economist described as a "firm radical." 

He, like most Iranians in power, does not believe in the existence of Israel. He defended the taking of hostages at the U.S. Embassy in Iran in 1979, which led to the break in ties between the countries. 

He was part of a regime that regularly executed dissidents and backed the fatwa against British author Salman Rushdie. 

And as late as April, he opposed suspending the country's nuclear-enrichment program but said it would not be diverted to weapons use. 

"I wouldn't go as far as (call it) a 'Velvet Revolution,'" Trita Parsi, president of the National Iranian American Council, said of the phrase many are using to describe the rallies in Iran.  QUESTIONS:
