Clashes in Libya between security forces and demonstrators during Thursday's "day of rage" left at least 20 protesters dead, according to news reports.
The harsh reaction to protests in recent days suggests that Moammar Gadhafi, who has ruled Libya since 1969, has no intention of surrendering power anytime soon.
"Personally, I don't think the chances of the protesters succeeding at this point are terribly high," says Dirk J. Vandewalle, a professor of government at Dartmouth College.
